The NetBSD Operating System is a fully functional Open Source UNIX-like operating system derived from the Univer- sity of California, Berkeley Networking Release 2 (Net/2), 4.4BSD-Lite, and 4.4BSD-Lite2 sources. NetBSD runs on many different different system architectures (ports) across a variety of distinct CPU families, and is being ported to more. The NetBSD 9.4_STABLE release contains complete binary releases for most of these system architectures, with preliminary support for the others included in source form. Please see the NetBSD website: https://www.NetBSD.org/ for information on them. NetBSD is a completely integrated system. In addition to its highly portable, high performance kernel, NetBSD fea- tures a complete set of user utilities, compilers for sev- eral languages, the X Window System, firewall software and numerous other tools, all accompanied by full source code. NetBSD is a creation of the members of the Internet commu- nity. Without the unique cooperation and coordination the net makes possible, NetBSD would not exist. Changes Between The NetBSD 8 and 9 Releases The NetBSD 9.4_STABLE release provides many significant changes, including support for many new devices, hundreds of bug fixes, new and updated kernel subsystems, and numerous userland enhancements. The result of these improvements is a stable operating system fit for production use that rivals most commercially available systems. It is impossible to completely summarize the massive devel- opment that went into the NetBSD 9.4_STABLE release. The complete list of changes can be found in the following files: CHANGES: https://nycdn.NetBSD.org/pub/NetBSD-daily/netbsd-9/latest/CHANGES CHANGES-9.1: https://nycdn.NetBSD.org/pub/NetBSD-daily/netbsd-9/latest/CHANGES-9.1 CHANGES-9.2: https://nycdn.NetBSD.org/pub/NetBSD-daily/netbsd-9/latest/CHANGES-9.2 CHANGES-9.3: https://nycdn.NetBSD.org/pub/NetBSD-daily/netbsd-9/latest/CHANGES-9.3 CHANGES-9.4: https://nycdn.NetBSD.org/pub/NetBSD-daily/netbsd-9/latest/CHANGES-9.4 CHANGES-9.5: https://nycdn.NetBSD.org/pub/NetBSD-daily/netbsd-9/latest/CHANGES-9.5 files in the top level directory of the NetBSD 9.4 release tree. Installation and Partitioning Changes The sysinst installation program has been reworked for this release. It now supports arbitrary big disks and offers GPT parti- tions as alternative to MBR/fdisk partitions on a lot archi- tectures. Unfortunately it has not been tested on all hardware sup- ported by NetBSD. If you have problems partitioning the target disk or installing the system, please report bugs with as much details as possible. See the Administrivia section below on how to report bugs or contact other users and ask for support. Features to be removed in a later release The following features are to be removed from NetBSD in the future: o groff(1). Man pages are now handled with mandoc(1), and groff(1) can still be found in pkgsrc as textproc/groff. The NetBSD Foundation The NetBSD Foundation is a tax exempt, not-for-profit 501(c)(3) corporation that devotes itself to the traditional goals and Spirit of the NetBSD Project and owns the trade- mark of the word ``NetBSD''. It supports the design, devel- opment, and adoption of NetBSD worldwide.

Depending on your system, these may be bootable. source/ Source distribution sets; see below. In addition to the files and directories listed above, there is one directory per architecture, for each of the architec- tures for which NetBSD 9.4_STABLE has a binary distribution. The source distribution sets can be found in subdirectories of the source subdirectory of the distribution tree. They contain the complete sources to the system. The source dis- tribution sets are as follows: gnusrc This set contains the ``gnu'' sources, including the source for the compiler, assembler, groff, and the other GNU utilities in the binary distribution sets. sharesrc This set contains the ``share'' sources, which include the sources for the man pages not associ- ated with any particular program; the sources for the typesettable document set; the dictionaries; and more. src This set contains all of the base NetBSD 9.4_STA- BLE sources which are not in gnusrc, sharesrc, or syssrc. syssrc This set contains the sources to the NetBSD 9.4_STABLE kernel for all architectures as well as the config(1) utility. xsrc This set contains the sources to the X Window Sys- tem. All the above source sets are located in the source/sets subdirectory of the distribution tree. The source sets are distributed as compressed tar files. Except for the pkgsrc set, which is traditionally unpacked into /usr/pkgsrc, all sets may be unpacked into /usr/src with the command: # cd / ; tar -zxpf set_name.tgz In each of the source distribution set directories, there are files which contain the checksums of the files in the directory: MD5 MD5 digests in the format produced by the com- mand: cksum -a MD5 file. SHA512 SHA512 digests in the format produced by the command: cksum -a SHA512 file. The SHA512 digest is safer, but MD5 checksums are provided so that a wider range of operating systems can check the integrity of the release files. NetBSD/sun2 subdirectory structure The sun2-specific portion of the NetBSD 9.4_STABLE release is found in the sun2 subdirectory of the distribution: .../NetBSD-9.4_STABLE/sun2/. It contains the following files and directories: INSTALL.html INSTALL.ps INSTALL.txt INSTALL.more Installation notes in various file formats, including this file. The .more file contains underlined text using the more(1) conventions for indicating italic and bold display. binary/ kernel/ netbsd-GENERIC.gz A gzipped NetBSD kernel containing code for every- thing supported in this release. sets/ sun2 binary distribution sets; see below. installation/ miniroot/ sun2 miniroot file system image; see below. misc/ Miscellaneous sun2 installation utilities; see installation section below. netboot/ Two programs needed to boot sun2 kernels over the network. tapeimage/ Tape boot program, and two shell scripts used to prepare tapes. Binary distribution sets The NetBSD sun2 binary distribution sets contain the bina- ries which comprise the NetBSD 9.4_STABLE release for sun2. The binary distribution sets can be found in the sun2/binary/sets subdirectory of the NetBSD 9.4_STABLE dis- tribution tree, and are as follows: base The NetBSD 9.4_STABLE sun2 base binary distribu- tion. You must install this distribution set. It contains the base NetBSD utilities that are neces- sary for the system to run and be minimally func- tional. comp Things needed for compiling programs. This set includes the system include files (/usr/include) and the various system libraries (except the shared libraries, which are included as part of the base set). This set also includes the manual pages for all of the utilities it contains, as well as the system call and library manual pages. debug This distribution set contains debug information for all base system utilities. It is useful when reporting issues with binaries or during develope- ment. This set is huge, if the target disk is small, do not install it. etc This distribution set contains the system configu- ration files that reside in /etc and in several other places. This set must be installed if you are installing the system from scratch, but should not be used if you are upgrading. games This set includes the games and their manual pages. kern-GENERIC This set contains a NetBSD/sun2 9.4_STABLE GENERIC kernel, named /netbsd. You must install this dis- tribution set. man This set includes all of the manual pages for the binaries and other software contained in the base set. Note that it does not include any of the man- ual pages that are included in the other sets. misc This set includes the system dictionaries, the typesettable document set, and other files from /usr/share. modules This set includes kernel modules to add functional- ity to a running system. rescue This set includes the statically linked emergency recover binaries installed in /rescue. text This set includes NetBSD's text processing tools, including groff(1), all related programs, and their manual pages. NetBSD maintains its own set of sources for the X Window System in order to assure tight integration and compatibil- ity. NetBSD/sun2 currently does not ship with an X server or X clients. The sun2 binary distribution sets are distributed as gzipped tar files named with the extension .tgz, e.g. base.tgz. The instructions given for extracting the source sets work equally well for the binary sets, but it is worth noting that if you use that method, the filenames stored in the sets are relative and therefore the files are extracted below the current directory. Therefore, if you want to extract the binaries into your system, i.e. replace the system binaries with them, you have to run the tar -xzpf command from the root directory ( / ) of your system. There is a collection of Sun2 kernels in the sun2/binary/kernel subdirectory of the NetBSD 9.4_STABLE distribution. The one named netbsd-RAMDISK.gz contain a root file system image and should only be used for the ini- tial installation. The others are included for convenience. (Most people will want to use netbsd-GENERIC.gz or netbsd-FOURMEG.gz as appropriate.) Please note that these kernels are simply gzipped and are not tar archives. Note: Each directory in the sun2 binary distribution also has its own checksum files, just as the source dis- tribution does. NetBSD/sun2 System Requirements and Supported Devices NetBSD/sun2 9.4_STABLE runs on Multibus Sun2 machines, including: 2/120 2/170 2/100U The minimal configuration requires 4 MB of RAM and about 130 MB of disk space. To install the entire system requires much more disk space. To compile the system, more RAM is recommended. Good performance requires 7 MB of RAM. A good rule of thumb is to have a swap partition twice the size of the amount of RAM in your machine. You will probably want to compile your own kernel, as GENERIC is large and bulky to accommodate all people. Note that the sun2 installation procedure uses a miniroot image which is placed into the swap area of the disk. The swap partition must be at least as large as the miniroot image (12 MB). Supported hardware o Serial ports (RS232) - built-in ttya, ttyb - ttyc, ttyd, ttye, ttyf on first sc SCSI - ttyg, ttyh, ttyi, ttyj on second sc SCSI o Video adapters - bwtwo o Network interfaces: - Multibus Intel Ethernet - Multibus 3Com Ethernet o SCSI - Most SCSI disks, tapes, CD-ROMs, etc - Multibus Sun-2 SCSI (sc) o Input devices - Sun keyboard and mouse o Miscellaneous - Battery-backed real-time clock. If it's not on this list, there is no support for it in this release. Getting the NetBSD System on to Useful Media Installation is supported from several media types, includ- ing: o Tape o NFS o CD-ROM o FTP Note: Installing on a `bare' machine requires some bootable device; either a tape drive or Sun-compatible NFS server. The procedure for transferring the distribution sets onto installation media depends on the type of media. Instruc- tions for each type of media are given below. In order to create installation media, you will need all the files in the directory .../NetBSD-9.4_STABLE/sun2/ Creating boot/install tapes Installing from tape is the simplest method of all. This method uses two tapes; one called the boot tape, and another called the install tape. The boot tape is created as follows: # cd .../NetBSD-9.4_STABLE/sun2/installation/tapeimage # sh MakeBootTape /dev/nrst0 The install tape is created as follows: # cd .../NetBSD-9.4_STABLE/sun2/installation/tapeimage # sh MakeInstallTape /dev/nrst0 If the tapes do not work as expected, you may need to explicitly set the EOF mark at the end of each tape segment. It may also be necessary to use the conv=osync argument to dd(1). Note that this argument is incompatible with the bs= argument. Consult the tape-related manual pages on the sys- tem where the tapes are created for more details. Boot/Install from NFS server If your machine has a disk and network connection, but no tape drive, it may be convenient for you to install NetBSD over the network. This involves temporarily booting your machine over NFS, just long enough so you can initialize its disk. This method requires that you have access to an NFS server on your network so you can configure it to support diskless boot for your machine. Configuring the NFS server is normally a task for a system administrator, and is not trivial. If you are using a NetBSD system as the boot-server, have a look at the diskless(8) manual page for guidelines on how to proceed with this. If the server runs another operating system, consult the documentation that came with it (i.e. add_client(8) on SunOS). When instructed to boot over the network, your sun2 expects to be able to download first and second stage bootstrap pro- grams via ND, the Network Disk protocol. The ndbootd(8) program will attempt to serve a second-stage bootstrap file using a name derived from the machine's recently acquired IP address and an extension which corresponds to the machine architecture. (It may be handy to have a hexadecimal calcu- lator for this next step.) The filename prefix is created by converting the machine's assigned IP address into hexa- decimal, most-significant octet first, using uppercase char- acters for the non-decimal (A-F) digits. The filename suf- fix used by all sun2 machines is SUN2. For example, a sun2 which has been assigned IP address 130.115.144.11 will be served a second-stage bootstrap file named 8273900B.SUN2. Normally, this file is a symbolic link to the NetBSD/sun2 netboot program, which should be located in a place where the ndbootd(8) daemon can find it. The netboot program may be found in the installation/netboot directory of this distribution. The netboot program will query a bootparamd server to find the NFS server address and path name for its root, and then load a kernel from that location. The server should have a copy of the netbsd-RAMDISK kernel in the root area for your client, hard-linked under the names netbsd and vmunix (no other files are needed in the client root) and /etc/bootparams on the server should have an entry for your client and its root directory. The client will need access to the miniroot image, which can be provided using NFS or remote shell. If you will be installing NetBSD on several clients, it may be useful to know that you can use a single NFS root for all the clients as long as they only use the netbsd-RAMDISK ker- nel. There will be no conflict between clients because the RAM-disk kernel will not use the NFS root. No swap file is needed; the RAM-disk kernel does not use that either. Install/Upgrade from CD-ROM This method requires that you boot from another device (i.e. tape or network, as described above). You may need to make a boot tape on another machine using the files provided on the CD-ROM. Once you have booted netbsd-rd (the RAM-disk kernel) and loaded the miniroot, you can load any of the distribu- tion sets directly from the CD-ROM. The install program in the miniroot automates the work required to mount the CD-ROM and extract the files. Install/Upgrade via FTP This method requires that you boot from another device (i.e. tape or network, as described above). You may need to make a boot tape on another machine using the files in installation/tapeimage and binary/kernel (which you get via FTP). Once you have booted netbsd-RAMDISK (the RAM-disk kernel) and loaded the miniroot, you can load any of the distribution sets over the net using FTP. The install pro- gram in the miniroot automates the work required to config- ure the network interface and transfer the files. The preparations for this installation/upgrade method are easy; all you make sure that there's some FTP site from which you can retrieve the NetBSD distribution when you're about to install or upgrade. You need to know the numeric IP address of that site, and, if it's not on a network directly connected to the machine on which you're installing or upgrading NetBSD, you need to know the numeric IP address of the router closest to the NetBSD machine. Finally, you need to know the numeric IP address of the NetBSD machine itself. Preparing your System for NetBSD installation Sun2 machines usually need little or no preparation before installing NetBSD, other than the usual, well advised pre- caution of backing up all data on any attached storage devices. You will need to know the SCSI target ID of the drive on which you will install NetBSD. Note: SunOS on the sun2 uses confusing names for the SCSI devices: target 1 is sd2, target 2 is sd4, etc. Installing the NetBSD System Installing NetBSD is a relatively complex process, but if you have this document in hand it should not be too diffi- cult. There are several ways to install NetBSD onto your disk. If your machine has a tape drive the easiest way is Installing from tape (details below). If your machine is on a network with a suitable NFS server, then Installing from NFS is the next best method. Otherwise, if you have another Sun machine running SunOS you can initialize the disk on that machine and then move the disk. (Installing from SunOS is not recommended.) Installing from tape Create the NetBSD/sun2 9.4_STABLE boot tape as described in the section entitled Creating boot/install tapes and boot the tape. At the PROM monitor prompt, use one of the com- mands: >b st() >b st(0,8,0) The first example will use the tape on SCSI target 4, where the second will use SCSI target 5. The > is the monitor prompt. After the tape loads, you should see many lines of configu- ration messages, and then the following `welcome' screen: Welcome to the NetBSD/sun2 RAMDISK root! This environment is designed to do only three things: 1: Partition your disk (use the command: edlabel /dev/rsd0c) 2: Copy a miniroot image into the swap partition (/dev/rsd0b) 3: Reboot (using the swap partition, i.e. /dev/sd?b). Note that the sun2 firmware cannot boot from a partition located more than 1 GB from the beginning of the disk, so the swap partition should be completely below the 1 GB boundary. Copying the miniroot can be done several ways, allowing the source of the miniroot image to be on any of these: boot tape, NFS server, TFTP server, rsh server The easiest is loading from tape, which is done as follows: mt -f /dev/nrst0 rewind mt -f /dev/nrst0 fsf 2 dd if=/dev/nrst0 of=/dev/rsd0b bs=32k conv=sync (For help with other methods, please see the install notes.) To reboot using the swap partition, first use "halt", then at the PROM monitor prompt use a command like: b sd(,,1) -s To view this message again, type: cat /.welcome Copy the miniroot as described in the welcome message, and reboot from that just installed miniroot. See the section entitled Booting the miniroot for details. Installing from NFS Before you can install from NFS, you must have already con- figured your NFS server to support your machine as a disk- less client. Instructions for configuring the server are found in the section entitled Getting the NetBSD System onto Useful Media above. First, at the Sun PROM monitor prompt, enter a boot command using the network interface as the boot device. If your machine has Intel Ethernet, this is ie, and if it has 3Com Ethernet, this is ec. Examples: >b ie() -s >b ec() -s After the boot program loads the RAMDISK kernel, you should see the welcome screen as shown in the Installing from tape section above. You must configure the network interface before you can use any network resources. For example the command: ssh> ifconfig ie0 inet 192.233.20.198 up will bring up the network interface with that address. The next step is to copy the miniroot from your server. This can be done using either NFS or remote shell. (In the exam- ples that follow, the server has IP address 192.233.20.195.) You may then need to add a default route if the server is on a different subnet: ssh> route add default 192.233.20.255 1 You can look at the route table using: ssh> route show Now mount the NFS file system containing the miniroot image: ssh> mount -o rdonly,-r=1024 192.233.20.195:/server/path /mnt The procedure is simpler and much faster if you have space for an expanded (not compressed) copy of the miniroot image. In that case: ssh> dd if=/mnt/miniroot.fs of=/dev/rsd0b bs=8k Otherwise, you will need to use zcat to expand the miniroot image while copying. This is tricky because the ssh program (small shell) does not handle sh(1) pipeline syntax. Instead, you first run the reader in the background with its input set to /dev/pipe and then run the other program in the foreground with its output to /dev/pipe. The result looks like this: ssh> run -bg dd if=/dev/pipe of=/dev/rsd0b obs=8k ssh> run -o /dev/pipe zcat /mnt/install/miniroot.fs.gz To load the miniroot using rsh to the server, you would use a pair of commands similar to the above. Here is another example: ssh> run -b dd if=/dev/pipe of=/dev/rsd0b obs=8k ssh> run -o /dev/pipe rsh 192.233.20.195 zcat miniroot.fs.gz Note that decompression on a sun2 is extremely slow, be pre- pared to wait. For this reason, expanding the miniroot image on the NFS server is highly recommended. Once the miniroot has been copied using one of the above methods, you reboot from that just installed miniroot. See the section entitled Booting the miniroot for details. Installing from SunOS To install NetBSD/sun2 onto a machine already running SunOS, you will need the miniroot image (miniroot.fs.gz) and some means to decompress it. First, boot SunOS and place the miniroot file onto the hard drive. If you do not have gzip for SunOS, you will need to decompress the image elsewhere before you can use it. Next, bring SunOS down to single user mode to insure that nothing will be using the swap space on your drive. To be extra safe, reboot the machine into single-user mode rather than using the shutdown command. Now copy the miniroot image onto your swap device (here /dev/rsd0b) with the command gzip -dc miniroot.fs.gz | dd of=/dev/rsd0b obs=32k or if you have already decompressed the miniroot dd if=miniroot.fs of=/dev/rsd0b obs=32k Finally, reboot the machine and instruct the PROM to boot from the swap device as described in the next section. Booting the Miniroot If the machine is not already at the PROM monitor, run the halt command. If the miniroot was installed on partition `b' of the disk with SCSI target ID=0 then the PROM boot command would be: >b sd(0,0,1) -s With SCSI target ID=2, the PROM is: >b sd(0,10,1) -s The numbers in parentheses above are: 1. controller (usually zero) 2. unit number (SCSI-ID * 8, in hexadecimal) 3. partition number Miniroot install program The miniroot's install program is very simple to use. It will guide you through the entire process, and is well auto- mated. Additional improvements are planned for future releases. The miniroot's install program will: o Allow you to place disklabels on additional disks. The disk we are installing on should already have been partitioned using the RAMDISK kernel. o Create file systems on target partitions. o Allow you to set up your system's network configu- ration. Remember to specify host names without the domain name appended to the end. For example use foo instead of foo.bar.org. If, during the process of configuring the network interfaces, you make a mistake, you will be able to re-configure that interface by simply selecting it for configu- ration again. o Mount target file systems. You will be given the opportunity to manually edit the resulting /etc/fstab. o Extract binary sets from the media of your choice. o Copy configuration information gathered during the installation process to your root file system (/). o Make device nodes in your root file system under /dev. o Copy a new kernel onto your root partition (/). o Install a new boot block. o Check your file systems for integrity. First-time installation on a system through a method other than the installation program is possible, but strongly dis- couraged. Post installation steps Once you've got the operating system running, there are a few things you need to do in order to bring the system into a properly configured state. The most important steps are described below. 1. Before all else, read postinstall(8). 2. Configuring /etc/rc.conf If you or the installation software haven't done any configuration of /etc/rc.conf (sysinst normally will), the system will drop you into single user mode on first reboot with the message /etc/rc.conf is not configured. Multiuser boot aborted. and with the root file system (/) mounted read-only. When the system asks you to choose a shell, simply press RETURN to get to a /bin/sh prompt. If you are asked for a terminal type, respond with vt220 (or what- ever is appropriate for your terminal type) and press RETURN. You may need to type one of the following com- mands to get your delete key to work properly, depend- ing on your keyboard: # stty erase '^h' # stty erase '^?' At this point, you need to configure at least one file in the /etc directory. You will need to mount your root file system read/write with: # /sbin/mount -u -w / Change to the /etc directory and take a look at the /etc/rc.conf file. Modify it to your tastes, making sure that you set rc_configured=YES so that your changes will be enabled and a multi-user boot can pro- ceed. Default values for the various programs can be found in /etc/defaults/rc.conf, where some in-line doc- umentation may be found. More complete documentation can be found in rc.conf(5). When you have finished editing /etc/rc.conf, type exit at the prompt to leave the single-user shell and con- tinue with the multi-user boot. Other values that may need to be set in /etc/rc.conf for a networked environment are hostname and possibly defaultroute. You may also need to add an ifconfig_int for your network interface, along the lines of ifconfig_le0="inet 192.0.2.123 netmask 255.255.255.0" or, if you have myname.my.dom in /etc/hosts: ifconfig_le0="inet myname.my.dom netmask 255.255.255.0" To enable proper hostname resolution, you will also want to add an /etc/resolv.conf file or (if you are feeling a little more adventurous) run named(8). See resolv.conf(5) or named(8) for more information. Instead of manually configuring networking, DHCP can be used by setting dhcpcd=YES in /etc/rc.conf. 3. Logging in After reboot, you can log in as root at the login prompt. If you didn't set a password in sysinst, there is no initial password. You should create an account for yourself (see below) and protect it and the ``root'' account with good passwords. By default, root login from the network is disabled (even via ssh(1)). One way to become root over the network is to log in as a different user that belongs to group ``wheel'' (see group(5)) and use su(1) to become root. 4. Adding accounts Use the useradd(8) command to add accounts to your sys- tem. Do not edit /etc/passwd directly! See vipw(8) and pwd_mkdb(8) if you want to edit the password database. 5. Installing third party packages If you wish to install any of the software freely available for UNIX-like systems you are strongly advised to first check the NetBSD package system, pkgsrc. pkgsrc automatically handles any changes nec- essary to make the software run on NetBSD. This includes the retrieval and installation of any other packages the software may depend upon. o More information on the package system is available at https://www.NetBSD.org/docs/software/packages.html o A list of available packages suitable for browsing is at https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/README.html o Precompiled binaries can be found at https://cdn.NetBSD.org/pub/pkgsrc/packages/NetBSD/ usually in the sun2/9.4_STABLE/All subdir. If you installed pkgin(1) in the sysinst post-installation configuration menu, you can use it to automatically install binary packages over the network. Assuming that /usr/pkg/etc/pkgin/repositories.conf is cor- rectly configured, you can install them with the following commands: # pkgin install tcsh # pkgin install bash # pkgin install perl # pkgin install apache # pkgin install kde # pkgin install firefox ... Note: Some mirror sites don't mirror the /pub/pkgsrc directory. The above commands will install the Tenex-csh and Bourne Again shells, the Perl programming language, Apache web server, KDE desktop environment and the Firefox web browser as well as all the packages they depend on. o If you did not install it from the sysinst post- installation configuration menu, the pkgsrc(7) framework for compiling packages can be obtained by retrieving the file https://cdn.NetBSD.org/pub/pkgsrc/stable/pkgsrc.tar.gz. It is typically extracted into /usr/pkgsrc (though other locations work fine) with the commands: # cd /usr # tar -zxpf pkgsrc.tar.gz After extracting, see the doc/pkgsrc.txt file in the extraction directory (e.g., /usr/pkgsrc/doc/pkgsrc.txt) for more information. 6. Misc o Edit /etc/mail/aliases to forward root mail to the right place. Don't forget to run newaliases(1) afterwards. o Edit /etc/rc.local to run any local daemons you use. o Many of the /etc files are documented in section 5 of the manual; so just invoking # man 5 filename is likely to give you more information on these files. Upgrading a previously-installed NetBSD System It is possible to easily upgrade your existing NetBSD/sun2 system using the upgrade program in the miniroot. If you wish to upgrade your system by this method, simply select the upgrade option once the miniroot has booted. The upgrade program with then guide you through the procedure. The upgrade program will: o Enable the network based on your system's current network configuration. o Mount your existing file systems. o Extract binary sets from the media of your choice. o Make new device nodes in your root file system under /dev. o Copy a new kernel onto your root partition (/). Note: the existing kernel will not be backed up; doing so would be pointless, since older kernels may not be capable of running NetBSD 9.4_STABLE executables. o Install a new boot block. o Check your file systems for integrity. Using the miniroot's upgrade program is the preferred method of upgrading your system. However, it is possible to upgrade your system manually. To do this, follow the following procedure: o Place at least the base binary set in a file sys- tem accessible to the target machine. A local file system is preferred, since the NFS subsystem in the NetBSD 9.4_STABLE kernel may be incompati- ble with your old binaries. o Back up your pre-existing kernel and copy the 9.4_STABLE kernel into your root partition (/). o Reboot with the 9.4_STABLE kernel into single-user mode. (Otherwise you can not install the boot block.) o Check all file systems: # /sbin/fsck -pf o Mount all local file systems: # /sbin/mount -a -t nonfs o If you keep /usr or /usr/share on an NFS server, you will want to mount those file systems as well. To do this, you will need to enable the network: # sh /etc/rc.d/network start o Make sure you are in the root file system (/ and extract the) base binary set: # cd / # pax -zrvpe -f Ar /path/to/base.tgz o Install a new boot block: (assuming root is on /dev/rsd0a) # cd /usr/mdec # cp -p ./ufsboot /mnt/ufsboot # sync ; sleep 1 ; sync # /usr/sbin/installboot -v /dev/rsd0a bootxx /ufsboot o Sync the file systems: sync o At this point you may extract any other binary sets you may have placed on local file systems, or you may wish to extract additional sets at a later time. To extract these sets, use the following commands: # cd / # pax -zrvpe -f path_to_set Note: You should not extract the etc set if upgrading. Instead, you should extract that set into another area and carefully merge the changes by hand. Compatibility Issues With Previous NetBSD Releases Users upgrading from previous versions of NetBSD may wish to bear the following problems and compatibility issues in mind when upgrading to NetBSD 9.4_STABLE. Note that sysinst will automatically invoke postinstall fix and thus all issues that are fixed by postinstall by default will be handled. A number of things have been removed from the NetBSD 9.4_STABLE release. See the ``Components removed from NetBSD'' section near the beginning of this document for a list. Using online NetBSD documentation Documentation is available if you installed the manual dis- tribution set. Traditionally, the ``man pages'' (documenta- tion) are denoted by `name(section)'. Some examples of this are o intro(1), o man(1), o apropos(1), o passwd(1), and o passwd(5). The section numbers group the topics into several cate- gories, but three are of primary interest: user commands are in section 1, file formats are in section 5, and administra- tive information is in section 8. The man command is used to view the documentation on a topic, and is started by entering man [section] topic. The brackets [] around the section should not be entered, but rather indicate that the section is optional. If you don't ask for a particular section, the topic with the lowest num- bered section name will be displayed. For instance, after logging in, enter # man passwd to read the documentation for passwd(1). To view the docu- mentation for passwd(5), enter # man 5 passwd instead. If you are unsure of what man page you are looking for, enter # apropos subject-word where subject-word is your topic of interest; a list of pos- sibly related man pages will be displayed. Administrivia If you've got something to say, do so! We'd like your input. There are various mailing lists available via the mailing list server at majordomo@NetBSD.org. See https://www.NetBSD.org/mailinglists/ for details. There are various mailing lists set up to deal with comments and questions about this release. Please send comments to: netbsd-comments@NetBSD.org. To report bugs, use the send-pr(1) command shipped with NetBSD, and fill in as much information about the problem as you can. Good bug reports include lots of details. Bugs also can be submitted and queried with the web inter- face at https://www.NetBSD.org/support/send-pr.html There are also port-specific mailing lists, to discuss aspects of each port of NetBSD. Use majordomo to find their addresses, or visit https://www.NetBSD.org/mailinglists/ If you're interested in doing a serious amount of work on a specific port, you probably should contact the `owner' of that port (listed below). If you'd like to help with NetBSD, and have an idea as to how you could be useful, send us mail or subscribe to: netbsd-users@NetBSD.org. As a favor, please avoid mailing huge documents or files to these mailing lists. Instead, put the material you would have sent up for FTP or WWW somewhere, then mail the appro- priate list about it. If you'd rather not do that, mail the list saying you'll send the data to those who want it. Thanks go to o The former members of UCB's Computer Systems Research Group, including (but not limited to): Keith Bostic Ralph Campbell Mike Karels Marshall Kirk McKusick for their work on BSD systems, support, and encourage- ment. o The Internet Systems Consortium, Inc. for hosting the NetBSD FTP, CVS, AnonCVS, mail, mail archive, GNATS, SUP, Rsync and WWW servers. o The Internet Research Institute in Japan for hosting the server which runs the CVSweb interface to the NetBSD source tree. o The Columbia University Computer Science Department for hosting the build cluster. o The many organizations that provide NetBSD mirror sites. o Without CVS, this project would be impossible to manage, so our hats go off to Brian Berliner, Jeff Polk, and the various other people who've had a hand in making CVS a useful tool. o We list the individuals and organizations that have made donations or loans of hardware and/or money, to support NetBSD development, and deserve credit for it at https://www.NetBSD.org/donations/ (If you're not on that list and should be, tell us! We probably were not able to get in touch with you, to ver- ify that you wanted to be listed.) o Finally, we thank all of the people who've put sweat and tears into developing NetBSD since its inception in Jan- uary, 1993. (Obviously, there are a lot more people who deserve thanks here. If you're one of them, and would like to be mentioned, tell us!)
