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, corresponding 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 release version number.
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 circumstances
(e.g., whether it's an official NetBSD snapshot, or not.)
All
MD5
files are MD5 digests for the various files in that directory, in the
format produced by the command:
cksum -m <file>.
All
SHA512
files are SHA512 digests for the various files in that directory, 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.
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
``/''.
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:
- 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, contain file systems that
have an internal layout that corresponds to
a complete release for a given machine type.
If built with
``iso-image-source'',
then it will also contain a
``source''
directory.
These images are usually bootable.
- MD5
-
- SHA512
-
- machine<.blm Ppcd.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 code of the operating system should be put into
.../NetBSD-<rel>/source/
using the following layout:
- sets/
-
Sources for the various system sets.
- MD5
-
- SHA512
-
- gnusrc.tgz
-
Contains sources for all GPLed and possibly other programs that
contains restrictions in their licensing that prevent others from
using these programs in closed-source environments.
- sharesrc.tgz
-
Contains machine-independent data files that can be shared across
architectures/systems.
- src.tgz
-
The operating system's userland source code, including all programs,
tools, libraries, 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>
/
fit the following layout:
- INSTALL.txt
-
Installation notes, including complete descriptions of files contained
within the release hierarchy
- INSTALL.more

functional.
This set excludes all things listed in the sets
described below.
