.Sh NAME
.Nm release
.Nd layout of NetBSD releases and snapshots
.Sh DESCRIPTION
This document describes the layout of
.Nx
releases and snapshots.
This layout should be consistent between FTP servers and CD-ROMs,
except possibly the path that leads to the release hierarchy.
.Pp
In this document, the following special words have these definitions:
.Bl -tag -width "<machine_arch>"
.It Em <machine>
The platform for which the release was built, corresponding to the
.Em hw.machine
sysctl variable, e.g.
.Em i386
or
.Em amiga .
.It Em <machine_arch>
The architecture for which a particular installation set was built,
corresponding to the
.Em hw.machine_arch
sysctl variable, e.g.
.Em i386
or
.Em m68k .
.It Em <rel>
The target release.
.El
.Pp
All
.Sy README
files are descriptions of the various files in directories that have
.Dq non-standard
contents.
.Pp
All
.Sy BSDSUM
files are historic BSD checksums for the various files in that directory,
in the format produced by the command:
.Sy cksum -o 1 <file> .
.Pp
All
.Sy CKSUM
files are POSIX checksums for the various files in that directory, in the
format produced by the command:
.Sy cksum <file> .
.Pp
All
.Sy MD5
files are MD5 digests for the various files in that directory, in the
format produced by the command:
.Sy cksum -m <file> .
.Pp
All
.Sy SYSVSUM
files are historic AT&T System V UNIX checksums for the various files in
that directory, in the format produced by the command:
.Sy cksum -o 2 <file> .
.Pp
The MD5 digest is the safest checksum, followed by the POSIX checksum.
The other two checksums are provided only to ensure that the widest possible
range of system can check the integrity of the release files.
.Pp
Files that end in
.Sy .tgz
are gzipped tar archives.  This is used in lieu of
.Sy .tar.gz
because the software used to download the sets may incorrectly auto-unpack
files ending in
.Sy .gz
and to accommodate systems which only support 3 character extensions
to file names.
.Pp
All tar archives are relative to the target's
.Sy /
directory, and
.Em do not
include the leading
.Dq / .
.Pp
All compression of release files is to be performed with the command:
.Sy gzip -9 .
.Pp
The root of the release hierarchy is
.Sm off
.Xo
.Sy .../NetBSD-
.Em <rel>
.Sy /
.Em <machine>
.Sy / .
.Xc
.Sm on
For files which may be shared by all systems of the same
.Em <machine_arch> ,
(e.g. the
.Sy games
and
.Sy xbase
sets for m68k-based platforms), this hierarchy will have a second root of
.Sm off
.Xo
.Sy .../NetBSD-
.Em <rel>
.Sy /
.Em <machine_arch>
.Sy /
.Xc
.Sm on
which will contain those files.  For files which are completely
machine-independent (e.g. the
.Sy xfont
set), this hierarchy will have a third root of
.Sy .../NetBSD- Ns Em <rel> Ns Sy /mi/
which will contain those files.
Unless otherwise noted, all files may be symbolic links to common
.Em <machine_arch>
or machine-independent files located in their respective directory
hierarchies.
.Bl -tag -width "installation/"
.It Sy 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:
.Sy date -u
.It Sy INSTALL
Installation notes, including complete descriptions of files contained
within the release hierarchy

functional.  It includes shared libraries for those architectures that
support support them.  This set excludes all things listed in the sets
described below.

manual pages.  It also includes the system include files
.Pq Pa /usr/include

software contained in the
.Sy base
set which are not included in the other sets.

This set includes the system dictionaries (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.
.It Sy text.tgz
This set includes the
.Nx
text processing tools, including
.Xr groff 1 ,
all related programs, and their manual pages.
