RELEASE(7) NetBSD Reference Manual RELEASE(7) NAME release - layout of NetBSD releases and snapshots DESCRIPTION This document describes the layout of NetBSD releases and snapshots. This layout should be consistent between FTP servers and CD-ROMs, except possibly the path that leads to the release hierarchy. In this document, the following special words have these definitions: The platform for which the release was built, correspond- ing to the hw.machine sysctl variable, e.g. i386 or amiga. The architecture for which a particular installation set was built, corresponding to the hw.machine_arch sysctl variable, e.g. i386 or m68k. The target release. All README files are descriptions of the various files in directories that have ``non-standard'' contents. All BSDSUM files are historic BSD checksums for the various files in that directory, in the format produced by the command: cksum -o 1 . All CKSUM files are POSIX checksums for the various files in that direc- tory, in the format produced by the command: cksum . All MD5 files are MD5 digests for the various files in that directory, in the format produced by the command: cksum -m . All SYSVSUM files are historic AT&T System V UNIX checksums for the vari- ous files in that directory, in the format produced by the command: cksum -o 2 . The MD5 digest is the safest checksum, followed by the POSIX checksum. The other two checksums are provided only to ensure that the widest pos- sible range of system can check the integrity of the release files. Files that end in .tgz are gzipped tar archives. This is used in lieu of .tar.gz because the software used to download the sets may incorrectly auto-unpack files ending in .gz and to accomodate systems which only sup- port 3 character extensions to file names. All tar archives are relative to the target's / directory, and do not in- clude the leading ``/''. All compression of release files is to be performed with the command: gzip -9. The root of the release hierarchy is .../NetBSD-//. For files which may be shared by all systems of the same , (e.g. the games and xbase sets for m68k-based platforms), this hierarchy will have a second root of .../NetBSD-// which will contain those files. For files which are completely machine-independent (e.g. the xfont set), this hierarchy will have a third root of .../NetBSD-/mi/ which will contain those files. Unless otherwise noted, all files may be symbolic links to common or ma- chine-independent files located in their respective directory hierar- chies. SOURCE_DATE a file containing the date, in UTC, of the source code from which the release or snapshot was built, in the de- fault format produced by the command: date -u INSTALL Installation notes, including complete descriptions of files contained within the release hierarchy binary/ system binaries sets/ installation sets BSDSUM CKSUM MD5 SYSVSUM Split/ installation sets split with the split(1) command. Note: split installation sets may not be available for all platforms. BSDSUM CKSUM MD5 SYSVSUM base.aa base.ab ... base.tgz The base binary distribution. This set contains the base NetBSD utilities that are necessary for the system to run and be minimal- ly functional. It includes shared libraries for those archi- tectures that support support them. This set excludes all things listed in the sets de- scribed below. comp.tgz The compiler tools distribution. This set contains the C and C++ compilers, assembler, linker, other toolchain components, and their manual pages. It also in- cludes the system include files (/usr/include) , and the static system libraries. etc.tgz This set contains the system con- figuration files that reside in /etc and in several other places throughout the file system hier- archy. games.tgz This set includes the games and their manual pages. kern.tgz This set includes a generic ker- nel. man.tgz This set includes all of the man- ual pages for the binaries and other software contained in the base set which are not included in the other sets. misc.tgz This set includes the system dic- tionaries (which are rather large), the typesettable document set, and manual pages for other architectures, which happen to be installed from the source tree by default. text.tgz This set includes the NetBSD text processing tools, including groff(1), all related programs, and their manual pages. xbase.tgz This set includes the base X11 distribution, including manual pages and shared libraries for those architectures that support them, and excluding everything contained in the other X11 sets. xcomp.tgz This set includes the X11 include files and static X11 libraries. xcontrib.tgz This set includes binaries and manual pages for programs built from the X11 ``contrib'' sources. xfont.tgz This set includes the X11 fonts. xserver.tgz This set includes the X servers and manual pages for . Note: this set may not be available on some platforms. kernel/ suitably named, gzipped kernels BSDSUM CKSUM MD5 README SYSVSUM netbsd-GENERIC.gz A kernel built from the GENERIC kernel configuration file. This is meant as an example only; different platforms may have differ- ently named kernels. security/ security-related system binaries BSDSUM CKSUM MD5 SYSVSUM Split/ BSDSUM CKSUM MD5 SYSVSUM secr.aa secr.ab ... secr.tgz This set contains executables which are built from the ``src/domestic'' portion of the NetBSD source tree. It can only be found on those sites which carry the complete NetBSD dis- tribution and can legally obtain it. (Remember, because of United States law, it may not be legal to dis- tribute this set to locations outside the United States and Canada.) installation/ installation helper items diskimage/ disk images, for those platforms that provide them BSDSUM CKSUM MD5 README SYSVSUM diskimage-rz25.gz floppy/ floppy images, for those platforms that pro- vide them BSDSUM CKSUM MD5 README SYSVSUM floppy-144.gz miniroot/ miniroot images, for those platforms that pro- vide them BSDSUM CKSUM MD5 README SYSVSUM miniroot.gz misc/ miscellaneous installation helper utilities, including boot selectors, floppy writing soft- ware, other software that runs under foreign operating systems, etc. BSDSUM CKSUM MD5 README SYSVSUM ... netboot/ network boot programs BSDSUM CKSUM MD5 README SYSVSUM netboot.gz tapeimage/ tape images, for those platforms that provide them BSDSUM CKSUM MD5 README SYSVSUM tapeimage-hp9144.gz SEE ALSO cksum(1), date(1), gzip(1), split(1), tar(1) HISTORY The release manual page first appeared in NetBSD 1.3.
