$NetBSD: INSTALL,v 1.50 1998/01/09 22:55:01 perry Exp $ INSTALLATION NOTES for NetBSD/_MACH _VER Be sure to read _ALL_ of this document before you try to install NetBSD/_MACH. What is NetBSD? ---- -- ------ The NetBSD Operating System is a fully functional UN*X-like system derived from the Berkeley Networking Release 2 (Net/2), 4.4BSD-Lite, and 4.4BSD-Lite2 sources. NetBSD runs on many architectures and is being ported to more. NetBSD is a creation of the members of the Internet community. Without the unique cooperation and coordination the net makes possible, it's likely that this release wouldn't have come about. The NetBSD _VER release is a landmark. Building upon the successful NetBSD 1.2 release, we have provided numerous and significant functional enhancements, including support for many new devices, integration of many bug fixes, new and updated kernel subsystems, and many userland enhancements. The results of these improvements is a stable operating system fit for production use that rivals most commercially available systems. It is impossible to summarize the 18 months of development that went into the NetBSD _VER release. Some of the significant changes include: Support for machine independent device drivers has been radically improved with the addition of the "bus.h" interface, providing a high quality abstraction for machine and architecture independent device access. The bus_dma interface has also been integrated, providing a machine-independent abstraction for DMA mapping. This permits many good things, including (among many) clean multi-platform bounce buffer support. Framework support for ISA "Plug and Play" has been added, as well as support for numerous "Plug and Play" devices. APM support has been added to NetBSD/i386. An initial cut of multi-platform PCMCIA support has been added. Support for ATAPI devices (initially just ATAPI CD-ROM drives) has been added. Support for Sun 3/80s (sun3x architecture) has been added. Support for R4000 DECstations has been added. Integration/merger of 4.4BSD Lite-2 sources into userland programs has nearly been completed. Most of userland now compiles with high levels of gcc warnings turned on, which has lead to the discovery and elimination of many bugs. The i386 boot blocks have been completely replaced with a new, libsa based two stage boot system. This has permitted integration of compressed boot support (see below). Many ports now support booting of compressed kernels, and feature new "Single Floppy" install systems that boot compressed install kernels and ramdisks. We intend to do substantial work on improving ease of installation in the future. "ypserv" has been added, thus completing our support for the "yp" network information system suite. Support for the Linux "ext2fs" filesystem and for FAT32 "msdosfs" filesystems has been added. TCP now has a SYN "compressed state engine" which provides increased robustness under high levels of received SYNs (as in the case of "SYN flood" attacks.) (Much of this code was derived from sources provided by BSDI.) An initial implementation of Path MTU discovery has been integrated (though it is not turned on by default). An initial kernel based random number generator pseudodevice has been added. Several major fixes have been integrated for the VM subsystem, including the fix of a notorious VM leak, improved synchronization between mmap()ed and open()ed files, and massively improved performance in low real memory conditions. A new swap subsystem has radically improved configuration and management of swap devices and adds swapping to files. Userland ntp support, including xntpd, has been integrated. The audio subsystems have been substantially debugged and improved, and now offer substantial emulation of the OSS audio interface, thus providing the ability to cleanly run emulated Linux and FreeBSD versions of sound intensive programs. A "packages" system has been adapted from FreeBSD and will provide binary package installations for third party applications. The XFree86 X source tree has been made a supported part of the NetBSD distribution, and X servers (if built for this port), libraries and utilities are now shipped with our releases. The ftp(1) program has been made astoundingly overfunctional. It supports command line editing, tab completion, status bars, automatic download of URLs specified on the command line, firewall support and many other features. All ports now use "new" config. Old config has been laid to rest. The ARP subsystem and API has been rewritten to make it less ethernet-centric. A new if_media subsystem has been added which allows network interfaces to be configured using media type names rather than device-specific mode bits. Many kernel interface manual pages have been added to manual section 9. Several ports support much more hardware. Many updates to bring NetBSD closer to standards compliance. Most third party packages have been updated to the latest stable release. As has been noted, there have also been innumerable bug fixes. Kernel interfaces have continued to be refined, and more subsystems and device drivers are shared among the different ports. You can look for this trend to continue. NetBSD _VER also includes some refinement to the NetBSD binary emulation system (which includes FreeBSD, HP-UX, iBCS2, Linux, OSF/1, SunOS, SVR4, Solaris and Ultrix compatibility), bringing NetBSD closer to the goal of making the emulation as accurate as possible. In the near future, we hope to integrate a fully rewritten Virtual Memory subsystem, kernel threads, and SMP support. #include "whatis" The Future of NetBSD: --- ------ -- ------ The NetBSD Foundation has been incorporated as a non-profit organization. Its purpose is to encourage, foster and promote the free exchange of computer software, namely the NetBSD Operating System. The foundation will allow for many things to be handled more smoothly than could be done with our previous informal organization. In particular, it provides the framework to deal with other parties that wish to become involved in the NetBSD Project. The NetBSD Foundation will help improve the quality of NetBSD by: * providing better organization to keep track of development efforts, including co-ordination with groups working in related fields. * providing a framework to receive donations of goods and services and to own the resources necessary to run the NetBSD Project. * providing a better position from which to undertake promotional activities. * periodically organizing workshops for developers and other interested people to discuss ongoing work. We hope to have regular releases of the full binary and source trees, but these are difficult to coordinate, especially with all of the architectures which we now support! We hope to support even _more_ hardware in the future, and have a rather large number of other ideas about what can be done to improve NetBSD. We intend to continue our current practice of making the NetBSD-current development source available on a daily basis. We intend to integrate free, positive changes from whatever sources will provide them, providing that they are well thought-out and increase the usability of the system. Above all, we hope to create a stable and accessible system, and to be responsive to the needs and desires of NetBSD users, because it is for and because of them that NetBSD exists. Sources of NetBSD: ------- -- ------ #include "mirrors" NetBSD _VER Release Contents: ------ --- ------- -------- The NetBSD _VER release is organized in the following way: .../NetBSD-_VER/ BUGS Known bugs list (incomplete and out of date). CHANGES Changes since NetBSD's last release (and before). LAST_MINUTE Last minute changes. MIRRORS A list of sites that mirror the NetBSD _VER distribution. README.files README describing the distribution's contents. TODO NetBSD's todo list (incomplete and out of date). patches/ Post-release source code patches. 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 architectures for which NetBSD _VER has a binary distribution. There are also 'README.export-control' files sprinkled liberally throughout the distribution tree, which point out that there are some portions of the distribution (i.e. the `domestic' portion) that may be subject to export regulations of the United States. It is your responsibility to determine whether or not it is legal for you to export these portions and to act accordingly. 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 distribution sets are as follows: secrsrc.tgz: This set contains the "domestic" sources. These sources may be subject to United States export regulations. [ 412K gzipped, 1.8M uncompressed ] gnusrc.tgz: This set contains the "gnu" sources, including the source for the compiler, assembler, groff, and the other GNU utilities in the binary distribution sets. [ 15.6M gzipped, 66.4M uncompressed ] syssrc.tgz: This set contains the sources to the NetBSD _VER kernel, config(8), and dbsym(8). [ 10.7M gzipped, 50.0M uncompressed ] sharesrc.tgz: This set contains the "share" sources, which include the sources for the man pages not associated with any particular program, the sources for the typesettable document set, the dictionaries, and more. [ 2.9M gzipped, 11.1M uncompressed ] src.tgz: This set contains all of the NetBSD _VER sources which are not mentioned above. [ 13.9M gzipped, 60.7M uncompressed ] Most of the above source sets are located in the source/sets subdirectory of the distribution tree. The secrsrc.tgz set is contained in the source/security subdirectory. This set, which is available only to users in the United States and Canada, contains the sources normally found in /usr/src/domestic -- primarily kerberos and other cryptographic security related software. (Remember, because of United States law, it may not be legal to distribute this set to locations outside of the United States and Canada.) The source sets are distributed as compressed tar files. They may be unpacked into /usr/src with the command: cat set_name.tgz | gunzip | (cd /; tar xpf - ) The sets/Split/ and security/Split/ subdirectories contain split versions of the source sets for those users who need to load the source sets from floppy or otherwise need a split distribution. The split sets are are named "set_name.xx" where "set_name" is the distribution set name, and "xx" is the sequence number of the file, starting with "aa" for the first file in the distribution set, then "ab" for the next, and so on. All of these files except the last one of each set should be exactly 240,640 bytes long. (The last file is just long enough to contain the remainder of the data for that distribution set.) The split distributions may be reassembled and extracted with "cat" as follows: cat set_name.?? | gunzip | (cd /; tar xpf - ) In each of the source distribution set directories, there is a file named "CKSUMS" which contains the checksums of the files in that directory, as generated by the cksum(1) utility. You can use cksum to check the integrity of the archives, if you suspect that one of the files is corrupt and have access to a cksum binary. Checksums based on other algorithms may also be present -- see the release(7) man page for details. #include "contents" NetBSD System Requirements and Supported Devices: ------ ------ ------------ --- --------- ------- #include "hardware" Getting the NetBSD System on to Useful Media: ------- --- ------ ------ -- -- ------ ----- #include "xfer" Preparing your System for NetBSD Installation: --------- ---- ------ --- ------ ------------ #include "prep" Installing the NetBSD System: ---------- --- ------ ------ #include "install" Upgrading a previously-installed NetBSD System: --------- - ---------- --------- ------ ------ #include "upgrade" 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 _VER: * Swap configuration Description: All swap partitions are now configured by the swapctl(8) program. The kernel no longer configures a "default" swap partition. Because of this, all swap partitions (even the old "default") must be listed in /etc/fstab. Many users of previous releases relied on the kernel configuring a "default" swap partition and did not list any swap space in /etc/fstab at all -- such users will now have no swap space configured unless they list swap partitions in /etc/fstab! Common symptoms of of this problem include machine crashes during builds, and similar memory intensive activities. Fix: The most common position for a swap partition is the `b' partition of the drive the root file system is on. For diskless systems, check the new swapctl(8) manual for more detail on how this is done. Example fstab entries: /dev/sd0b none swap sw,priority=0 /dev/sd1b none swap sw,priority=5 * NFS daemons and other programs in /sbin moved Description: The NFS daemons (nfsd, nfsiod, mountd) have been moved from the /sbin to the /usr/sbin directory. When new binaries are loaded over old ones during upgrade, most programs get overlaid and replaced, but unless these binaries are explicitly removed they will not disappear. The installation subsystems on some NetBSD architectures will not properly remove these binaries. Due to changes in the NFS subsystem, the old NFS daemon binaries will not work correctly, and will cause serious problems. Unfortunately, the default startup script (/etc/rc) will run the old binaries in /sbin if they are present instead of the new ones in /usr/sbin. Some other programs (dumpfs, dumplfs and quotacheck) have also been moved from /sbin to /usr/sbin, and old versions may be left behind by accident. They, too, may cause difficulties. Fix: Remove the old daemon binaries (/sbin/nfsiod, /sbin/nfsd, /sbin/mountd, etc.) after your upgrade has finished. You may wish to do an "ls -lt /sbin | more" to help determine which binaries were not replaced/removed during your upgrade. * AMANDA, The Advanced Maryland Automatic Network Disk Archiver, from http://www.amanda.org Description: Due to a change in the output of dump(8) to ensure consistency in the messages, AMANDA's dump output parser breaks. Error messages such as the following may be an indication that this problem is present: FAILURE AND STRANGE DUMP SUMMARY: hostname wd0e lev 1 FAILED [no backup size line] Versions affected: 2.3.0.4, and most likely earlier versions Workaround/Fix: One of: * Apply the patch found at: ftp://ftp.netbsd.org/pub/NetBSD/misc/patches/amanda-pre-2.4.patch * Upgrade to AMANDA 2.4.0 or newer. The side effect of this is that the network protocol is incompatible with earlier versions. Using online NetBSD documentation ----- ------ ------ ------------- Documentation is available if you first install the manual distribution set. Traditionally, the "man pages" (documentation) are denoted by 'name(section)'. Some examples of this are intro(1), man(1), apropros(1), passwd(1), and passwd(5). The section numbers group the topics into several categories, but three are of primary interest: user commands are in section 1, file formats are in section 5, and administrative 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 least-numbered section name will be displayed. For instance, after logging in, enter man passwd to read the documentation for passwd(1). To view the documentation 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 possibly 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 . To get help on using the mailing list server, send mail to that address with an empty body, and it will reply with instructions. 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' command shipped with NetBSD, and fill in as much information about the problem as you can. Good bug reports include lots of details. Additionally, bug reports can be sent by mail to: netbsd-bugs@NetBSD.ORG Use of 'send-pr' is encouraged, however, because bugs reported with it are entered into the NetBSD bugs database, and thus can't slip through the cracks. There are also port-specific mailing lists, to discuss aspects of each port of NetBSD. Use majordomo to find their addresses. 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 this effort, and have an idea as to how you could be useful, send mail and/or subscribe to: netbsd-help@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 somewhere, then mail the appropriate list about it, or, if you'd rather not do that, mail the list saying you'll send the data to those who want it. Thanks go to: ------ -- -- Members and 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 ongoing work on BSD systems, support, and encouragement. Also, our thanks go to: Mike Hibler Rick Macklem Jan-Simon Pendry Chris Torek for answering lots of questions, fixing bugs, and doing the various work they've done. UC Berkeley's Experimental Computing Facility provided a home for sun-lamp in the past, people to look after it, and a sense of humor. Rob Robertson, too, has added his unique sense of humor to things, and for a long time provided the primary FTP site for NetBSD. Best Internet Communications for hosting the NetBSD FTP and SUP server. Cygnus Support for hosting the NetBSD Mail server. 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. Dave Burgess has been maintaining the 386BSD/NetBSD/FreeBSD FAQ for quite some time, and deserves to be recognized for it. The following people (in alphabetical order) have made donations or loans of hardware and/or money, to support NetBSD development, and deserve credit for it: #include "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 verify that you wanted to be listed.) Finally, we thank all of the people who've put sweat and tears into developing NetBSD since its inception in January, 1993. (Obviously, there are a lot more people who deserve thanks here. If you're one of them, and would like to mentioned, tell us!) We are: -- --- (in alphabetical order) The NetBSD core group: J.T.

A doctoral student in Mathematical Science at Nagoya University, he was a user of NetBSD and a contributor to the project since 1993. Well remembered by his friends, he was also known as a connoisseur of gins, teas, and the motorcycles he loved to ride. His death came as a shock, and he will be greatly missed by all of us. May he rest in peace.
