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 9.2 release contains complete binary releases for most of these system architectures, with pre- liminary 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 9.2 release provides many significant changes, including support for many new devices, hundreds of bug fixes, new and updated kernel subsystems, and numerous user- land 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 9.2 release. The complete list of changes can be found in the following files: CHANGES: https://cdn.NetBSD.org/pub/NetBSD/NetBSD-9.2/CHANGES CHANGES-9.1: https://cdn.NetBSD.org/pub/NetBSD/NetBSD-9.2/CHANGES-9.1 CHANGES-9.2: https://cdn.NetBSD.org/pub/NetBSD/NetBSD-9.2/CHANGES-9.2 files in the top level directory of the NetBSD 9.2 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. More information on the NetBSD Foundation, its composition, aims, and work can be found at: https://www.NetBSD.org/foundation/ Sources of NetBSD Refer to mirrors: https://www.NetBSD.org/mirrors/ NetBSD 9.2 Release Contents The root directory of the NetBSD 9.2 release is organized as follows: .../NetBSD-9.2/ CHANGES Changes between the 8.0 and 9.0 releases. CHANGES-9.0 Changes between the initial 9.0 branch and final release of 9.0. CHANGES-9.1 Changes between the 9.0 and the 9.1 release. CHANGES-9.2 Changes between the 9.1 and the 9.2 release. CHANGES.prev Changes in previous NetBSD releases. LAST_MINUTE Last minute changes and notes about the release. README.files README describing the distribution's contents. images/ Images (ISO 9660 or USB) for installing NetBSD. 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 9.2 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 9.2 sources which are not in gnusrc, sharesrc, or syssrc. syssrc This set contains the sources to the NetBSD 9.2 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/rs6000 subdirectory structure The rs6000-specific portion of the NetBSD 9.2 release is found in the rs6000 subdirectory of the distribution: .../NetBSD-9.2/rs6000/. 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/ rs6000 binary distribution sets; see below. installation/ misc/ Miscellaneous rs6000 installation utilities; see installation section below. Binary distribution sets The NetBSD rs6000 binary distribution sets contain the bina- ries which comprise the NetBSD 9.2 release for rs6000. The binary distribution sets can be found in the rs6000/binary/sets subdirectory of the NetBSD 9.2 distribu- tion tree, and are as follows: base The NetBSD 9.2 rs6000 base binary distribution. You must install this distribution set. It con- tains the base NetBSD utilities that are necessary for the system to run and be minimally functional. 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/rs6000 9.2 GENERIC ker- nel, named /netbsd. You must install this distri- bution 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. These sources are based on X.Org. Binary sets for the X Window System are distributed with NetBSD. The sets are: xbase The basic files needed for a complete X client environment. This does not include the X servers. xcomp The extra libraries and include files needed to compile X source code. xdebug This distribution set contains debug information for all X11 binaries. It is useful when reporting issues with these binaries or during developement. This set is huge, if the target disk is small, do not install it. xfont Fonts needed by the X server and by X clients. xetc Configuration files for X which could be locally modified. xserver The X server. The rs6000 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. Note: Each directory in the rs6000 binary distribution also has its own checksum files, just as the source dis- tribution does. NetBSD/rs6000 System Requirements and Supported Devices Since NetBSD/rs6000 is an experimental port, the hardware support is in a constant state of flux. Check the port-prep@NetBSD.org mailing list and the NetBSD/rs6000 port homepage for an up-to-date list of known supported hardware. http://www.NetBSD.org/ports/rs6000/ NetBSD/rs6000 9.2 works diskless via netboot. Getting the NetBSD System on to Useful Media Installation is supported from several media types, includ- ing: o CD-ROM / DVD / USB-stick o FTP o Remote NFS partition o Tape o Existing NetBSD partitions, if performing an upgrade The steps necessary to prepare the distribution sets for installation depend upon which installation medium you choose. The steps for the various media are outlined below. CD-ROM / DVD / USB-stick Find out where the distribution set files are on the CD-ROM, DVD or USB stick. Likely locations are binary/sets and rs6000/binary/sets. (You only need to know this if you are mix- ing installer and installation media from different versions - the installer will know the proper default location for the sets it comes with). Proceed to the instructions on installation. FTP The preparations for this instal- lation/upgrade method are easy; all you need to do is make sure that there's an FTP site from which you can retrieve the NetBSD distribution when you're about to install or upgrade. If you don't have DHCP available on your net- work, you will 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. Once you have this information, you can proceed to the next step in the installation or upgrade process. If you're installing NetBSD from scratch, go to the section on preparing your hard disk, below. If you're upgrading an existing installation, go directly to the section on upgrad- ing. NFS Place the NetBSD distribution sets you wish to install into a direc- tory on an NFS server, and make that directory mountable by the machine on which you are installing or upgrading NetBSD. This will probably require modify- ing the /etc/exports file on the NFS server and resetting its mount daemon (mountd). (Both of these actions will probably require superuser privileges on the server.) You need to know the numeric IP address of the NFS server, and, if you don't have DHCP available on your network and the server is 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. Once the NFS server is set up properly and you have the informa- tion mentioned above, you can pro- ceed to the next step in the installation or upgrade process. If you're installing NetBSD from scratch, go to the section on pre- paring your hard disk, below. If you're upgrading an existing installation, go directly to the section on upgrading. Tape To install NetBSD from a tape, you need to make a tape that contains the distribution set files, in `tar' format. If you're making the tape on a UNIX-like system, the easiest way to do so is probably something like: # tar -cf tape_device dist_sets where tape_device is the name of the tape device that represents the tape drive you're using. This might be /dev/rst0, or something similar, but it will vary from system to system. In the above example, dist_sets is a list of filenames corresponding to the distribution sets that you wish to place on the tape. For instance, to put the kern-GENERIC, base, and etc distributions on tape (the absolute minimum required for installation), you would do the following: # cd .../NetBSD-9.2 # cd rs6000/binary # tar -cf tape_device kern-GENERIC.tgz base.tgz etc.tgz Note: You still need to fill in tape_device in the example. Once you have the files on the tape, you can proceed to the next step in the installation or upgrade process. If you're installing NetBSD from scratch, go to the section on preparing your hard disk, below. If you're upgrading an existing installa- tion, go directly to the section on upgrading. Preparing your System for NetBSD installation Installing the NetBSD System Installing NetBSD by using a netboot setup 1. Introduction To netboot a rs6000, you must configure one or more servers to provide information and files to your rs6000 (the `client'). If you are using NetBSD (any architec- ture) on your netboot server(s), the information pro- vided here should be sufficient to configure every- thing. Additionally, you may wish to look at the diskless(8) manual page and the manual pages for each daemon you'll be configuring. If the server(s) are another operating system, you should consult the NetBSD Diskless HOW-TO, which will walk you through the steps necessary to configure the netboot services on a vari- ety of platforms: https://www.NetBSD.org/docs/network/netboot/ You may either netboot the installer so you can install onto a locally attached disk, or you may run your sys- tem entirely over the network. Briefly, the netboot process involves discovery, boot- strap, kernel and file system stages. In the first stage, the client discovers information about where to find the bootstrap program. Next, it downloads and executes the bootstrap program. The bootstrap program goes through another discovery phase to determine where the kernel is located. The bootstrap program tries to mount the NFS share containing the kernel. Once the kernel is loaded, it starts executing. For RAM disk kernels, it mounts the RAM disk file system and begins executing the installer from the RAM disk. For normal (non-RAM disk) kernels, the kernel tries to mount the NFS share that had the kernel and starts executing the installation tools or init(8). TFTP is used in the bootstrap phase to download NFS is used in both the kernel and file system stages to download the kernel, and to access files on the file server. We will use `CC:CC:CC:CC:CC:CC' as the MAC address (ethernet hardware address) of your netboot client machine. You should have determined this address in an earlier stage. In this example, we will use `192.168.1.10' as the IP address of your client and `client.test.net' as its name. We will assume you're providing all of your netboot services on one machine called `server.test.net' with the client's files exported from the directory /export/client/root. You should, of course, replace all of these with the names, addresses, and paths appropriate to your environment. You should set up each netboot stage in order (i.e., discovery, bootstrap, kernel, and then file system) so that you can test them as you proceed. 2. 3. tftpd(8) The default configuration of the TFTP server is to run in a chroot(8) environment in the /tftpboot directory. Thus, the first order of business is to create this directory: # mkdir -p /tftpboot Next, edit /etc/inetd.conf and uncomment the line with the TFTP daemon: tftp dgram udp wait root /usr/libexec/tftpd tftpd -l -s /tftpboot Now, restart inetd(8). If the server is running NetBSD, you can achieve this with: # /etc/rc.d/inetd restart Now, you need to copy the bootloader for your rs6000 machine to /tftpboot. Just to be sure, let's make everything readable. # chmod -R a+rX /tftpboot Sometimes, the arp(8) table gets messed up, and the TFTP server can't communicate with the client. In this case, it will write a log message (via syslogd(8)) to /var/log/messages saying: `tftpd: write: Host is down'. If this is the case, you may need to force the server to map your client's ethernet address to its IP address: # arp -s client CC:CC:CC:CC:CC:CC 4. nfsd(8), mountd(8), and rpcbind(8) Now your system should be able to load the bootstrap program and start looking for the kernel. Let's set up the NFS server. Create the directory you are exporting for the netboot client: # mkdir -p /export/client/root Put the following line in /etc/exports to enable NFS sharing: /export/client/root -maproot=root client.test.net If your server is currently running an NFS server, you only need to restart mountd(8). Otherwise, you need to start rpcbind(8) and nfsd(8). If the server is running NetBSD, you can achieve this with: # /etc/rc.d/rpcbind start # /etc/rc.d/nfsd start # /etc/rc.d/mountd restart 5. NetBSD kernel and installation tools Now, if you place a kernel named netbsd in /export/client/root your client should boot the kernel. 6. Client file system You can skip this step if you do not plan to run your client diskless after installation. Otherwise, you need to extract and set up the client's installation of NetBSD. The Diskless HOW-TO describes how to provide better security and save space on the NFS server over the procedure listed here. See for details: https://www.NetBSD.org/docs/network/netboot/nfs.html. o Extracting distribution sets # cd /export/client/root # tar -xpzf /path/to/files/base.tgz # tar -xpzf /path/to/files/etc.tgz Continue with the other non-essential distribution sets if desired. o Set up swap # mkdir /export/client/root/swap # dd if=/dev/zero of=/export/client/swap bs=4k count=4k # echo '/export/client/swap -maproot=root:wheel client.test.net' >> /etc/exports # /etc/rc.d/mountd restart This creates a 16 MB swap file and exports it to the client. o Create device nodes # cd /export/client/root/dev # ./MAKEDEV all This procedure only works on NetBSD hosts. o Set up the client's fstab(5) Create a file in /export/client/root/etc/fstab with the following lines: server:/export/client/swap none swap sw,nfsmntpt=/swap server:/export/client/root / nfs rw 0 0 o Set up the client's rc.conf(5) Edit /export/client/root/etc/rc.conf rc_configured=YES hostname="client" defaultroute="192.168.1.1" nfs_client=YES auto_ifconfig=NO net_interfaces="" Make sure rc does not reconfigure the network device since it will lose its connection to the NFS server with your root file system. o Set up the client's hosts(5) file. Edit /export/client/root/etc/hosts ::1 localhost 127.0.0.1 localhost 192.168.1.10 client.test.net client 192.168.1.5 server.test.net server 7. Setting up the server daemons If you want these services to start up every time you boot your server, make sure the following lines are present in your /etc/rc.conf: nfs_server=YES # enable server daemons mountd=YES rpcbind=YES rpcbind_flags="-l" # -l logs libwrap Also, you'll need to make sure the tftpd line in /etc/inetd.conf remains uncommented. 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. The X Window System If you installed the X Window System, you may want to read the chapter about X in the NetBSD Guide: https://www.NetBSD.org/docs/guide/en/chap-x.html: 6. 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 rs6000/9.2/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/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. 7. 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 The easiest way to upgrade to NetBSD 9.2 is with binaries, and that is the method documented here. To do the upgrade, you must have one form of boot media available. You must also have at least the base and kern binary distribution sets available. Finally, you must have sufficient disk space available to install the new binaries. Since files already installed on the system are overwritten in place, you only need additional free space for files which weren't previously installed or to account for growth of the sets between releases. Since upgrading involves replacing the kernel, boot blocks, and most of the system binaries, it has the potential to cause data loss. You are strongly advised to back up any important data on the NetBSD partition or on another operat- ing system's partition on your disk before beginning the upgrade process. The upgrade procedure is similar to an installation, but without the hard disk partitioning. Fetching the binary sets is done in the same manner as the installation procedure; refer to the installation part of the document for help. File systems are checked before unpacking the sets. After a new kernel has been copied to your hard disk, your machine is a complete NetBSD 9.2 system. However, that doesn't mean that you're finished with the upgrade process. You will probably want to update the set of device nodes you have in /dev. If you've changed the contents of /dev by hand, you will need to be careful about this, but if not, you can just cd into /dev, and run the command: # sh MAKEDEV all sysinst will attempt to merge the settings stored in your /etc directory with the new version of NetBSD using the postinstall(8) utility. However, postinstall(8) is only able to deal with changes that are easily automated. It is recommended that you use the etcupdate(8) tool to merge any remaining configuration changes. 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 9.2. 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 9.2 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!)
