31.Dt RELEASE 7
32.Os
33.Sh NAME
34.Nm release
35.Nd layout of NetBSD releases and snapshots
36.Sh DESCRIPTION
37This document describes the layout of
38.Nx
39releases and snapshots.
40This layout should be consistent between FTP servers and CD-ROMs,
41except possibly the path that leads to the release hierarchy.
42.Pp
43In this document, the following special words have these definitions:
44.Bl -tag -width "\*[Lt]machine_arch\*[Gt]"
45.It Em \*[Lt]machine\*[Gt]
46The platform for which the release was built, corresponding to the
47.Em hw.machine
48sysctl variable, e.g.
49.Em i386
50or
51.Em amiga .
52.It Em \*[Lt]machine_arch\*[Gt]
53The architecture for which a particular installation set was built,
54corresponding to the
55.Em hw.machine_arch
56sysctl variable, e.g.
57.Em i386
58or
59.Em m68k .
60.It Em \*[Lt]rel\*[Gt]
61The target release.
62.El
63.Pp
64All
65.Sy README
66files are descriptions of the various files in directories that have
67.Dq non-standard
68contents.
69There may also be a
70.Sy README
71file at the top-level,
72describing who built the snapshot and under what circumstances
73.Po e.g. whether it's an official
74.Nx
75snapshot, or not
76.Pc .
77.Pp
78All
79.Sy BSDSUM
80files are historic
81.Bx
82checksums for the various files in that directory,
83in the format produced by the command:
84.Sy cksum -o 1 \*[Lt]file\*[Gt] .
85.Pp
86All
87.Sy CKSUM
88files are POSIX checksums for the various files in that directory, in the
89format produced by the command:
90.Sy cksum \*[Lt]file\*[Gt] .
91.Pp
92All
93.Sy MD5
94files are MD5 digests for the various files in that directory, in the
95format produced by the command:
96.Sy cksum -m \*[Lt]file\*[Gt] .
97.Pp
98All
99.Sy SYSVSUM
100files are historic
101.At V
102checksums for the various files in
103that directory, in the format produced by the command:
104.Sy cksum -o 2 \*[Lt]file\*[Gt] .
105.Pp
106The MD5 digest is the safest checksum, followed by the POSIX checksum.
107The other two checksums are provided only to ensure that the widest possible
108range of system can check the integrity of the release files.
109.Pp
110Files that end in
111.Sy .tgz
112are gzipped tar archives.  This is used in lieu of
113.Sy .tar.gz
114because the software used to download the sets may incorrectly auto-unpack
115files ending in
116.Sy .gz
117and to accommodate systems which only support 3 character extensions
118to file names.
119.Pp
120All tar archives are relative to the target's
121.Sy /
122directory, and
123.Em do not
124include the leading
125.Dq / .
126.Pp
127All compression of release files is to be performed with the command:
128.Sy gzip -9 .
129.Pp
130The root of the release hierarchy may be the root directory of a
131CD-ROM, but in all other cases it should be
132.Sm off
133.Xo
134.Sy .../NetBSD-
135.Em \*[Lt]rel\*[Gt]
136.Sy / .
137.Xc
138.Sm on
139.Pp
140The root of the release hierarchy should contain the following
141files and subdirectories:
142.Pp
143.Bl -tag -width "\*[Lt]machine\*[Gt]"
144.It Sy SOURCE_DATE
145A file containing the date, in UTC, of the source code from which the
146release or snapshot was built, in the default format produced by the
147command:
148.Sy date -u .
149.
150.It Sy iso/
151CDROM images in ISO 9660 format, usually created with
152.Dq ./build.sh ... iso-image ...

155in
156.Pa src

159after a
160.Dq ./build.sh -x ... release sourcesets ...
161in
162.Pa src .
163.Pp
164Images in this directory, unlike images in the
165.Sm off
166.Xo
167.Sy .../NetBSD-

169.Sy /

174directory, should contain file systems that
175have an internal layout that corresponds to
176a complete release for one or more machine types.
177If built with
178.Dq iso-image-source ,
179then it will also contain a
180.Dq source
181directory.
182These images are usually bootable.
