RELEASE(7) NetBSD Miscellaneous Information 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: <machine> The platform for which the release was built, correspond- ing to the hw.machine sysctl variable, e.g. i386 or amiga. <machine_arch> The architecture for which a particular installation set was built, corresponding to the hw.machine_arch sysctl variable, e.g. i386 or m68k. <rel> The target release. All README files are descriptions of the various files in directories that have ``non-standard'' contents. There may also be a README file at the top-level, describing who built the snapshot and under what circum- stances (e.g. whether it's an official NetBSD snapshot, or not). All BSDSUM files are historic BSD checksums for the various files in that directory, in the format produced by the command: cksum -o 1 <file>. All CKSUM files are POSIX checksums for the various files in that direc- tory, in the format produced by the command: cksum <file>. All MD5 files are MD5 digests for the various files in that directory, in the format produced by the command: cksum -m <file>. 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 <file>. 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 accommodate systems which only support 3 character extensions to file names. All tar archives are relative to the target's / directory, and do not include the leading ``/''. All compression of release files is to be performed with the command: gzip -9. The root of the release hierarchy may be the root directory of a CD-ROM, but in all other cases it should be .../NetBSD-<rel>/. The root of the release hierarchy should contain the following files and subdirectories: SOURCE_DATE A file containing the date, in UTC, of the source code from which the release or snapshot was built, in the default format produced by the command: date -u. iso/ CDROM images in ISO 9660 format, usually created with ``./build.sh ... iso-image ...'' after a ``./build.sh -x ... release ...'' in src or created with ``./build.sh ... iso-image-source ...'' after a ``./build.sh -x ... release sourcesets ...'' in src. Images in this directory, unlike images in the .../NetBSD-<rel>/<machine>/installation/cdrom/ directory, should contain file systems that have an internal layout that corresponds to a complete release for one or more machine types. If built with ``iso-image-source'', then it will also contain a ``source'' directory. These images are usually bootable. BSDSUM CKSUM MD5 README SYSVSUM <machine_arch>cd.iso shared/ Files shared by two or more machine types. <machine_arch>/ Files which may be shared by all systems of the same <machine_arch> will be located in .../NetBSD-<rel>/shared/<machine_arch>/ with symbolic links pointing to these files from the <machine> subdirectory. ALL/ Files which are completely machine-independent will be located in .../NetBSD-<rel>/shared/ALL/ with symbolic links pointing to these files from the <machine> subdirectory. source/ Source codes of the operating system and patches for it should be put into .../NetBSD-<rel>/source/ using the following lay- out: patches/ This directory contains various patch files appro- priate for patch(1). Other patches may exist for fixing critical problems. BSDSUM CKSUM MD5 README SYSVSUM diff-<lastrel>-<rel>.gz Diff against the last release, usually generated by cvs rdiff. For patch releases, diffs against the last release are included. If the last release was a patch release itself, the diff is against that patch release is included. sets/ Sources for the various system sets, based on their modules in the CVS server. BSDSUM CKSUM MD5 README SYSVSUM gnusrc.tgz Contains sources for all GPLed and possibly other programs that contains restrictions in their licensing that prevent others from using these pro- grams in closed-source environments. pkgsrc.tgz Package-sources for third party soft- ware ready to compile. See pkgsrc/README for more information. sharesrc.tgz Contains machine-independent data files that can be shared across archi- tectures/systems. src.tgz The operating system's userland source code, including all programs, tools, toolchain, etc. syssrc.tgz Kernel sources for all architectures plus sources of the tools needed to build kernels (like config(1)). xsrc.tgz Source code of the X Window System used on all NetBSD architectures. Includes X clients and servers. <machine>/ The binary releases in .../NetBSD-<rel>/<machine>/ follow the following layout: INSTALL.txt Installation notes, including complete descrip- tions of files contained within the release hierarchy INSTALL.more pretty version of this, suited for viewing with more(1) INSTALL.html HTML version of this INSTALL.ps PostScript version of this binary/ system binaries sets/ installation sets BSDSUM CKSUM MD5 SYSVSUM base.tgz The base binary distri- bution. This set con- tains the base NetBSD utilities that are nec- essary for the system to run and be minimally functional. It includes shared libraries for those architectures that sup- port them. This set excludes all things listed in the sets described below. comp.tgz The compiler tools dis- tribution. This set contains the C and C++ compilers, assembler, linker, other toolchain components, and their manual pages. It also includes the system include files (/usr/include) , and the static system libraries. etc.tgz This set contains the system configuration files that reside in /etc and in several other places throughout the file system hierar- chy. games.tgz This set includes the games and their manual pages. kern.tgz This set includes a generic kernel. man.tgz This set includes all of the manual 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 dictionaries (which are rather large), the typeset- table 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 bina- ries 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 <machine>. 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 configura- tion file. This is meant as an example only; dif- ferent platforms may have differ- ently named ker- nels. installation/ installation helper items cdrom/ CDROM images in ISO 9660 format, usually created as part of ``build.sh ... release ...'' in src. Images in this directory will typi- cally be bootable, and will contain one or more of a kernel, installa- tion tools, and rescue tools. They will not contain installation sets, source sets, or other components of a complete release.
