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 Aq Em machine
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 Aq Em machine_arch
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 Aq Em rel
61The release version number.
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 MD5
80files are MD5 digests for the various files in that directory, in the
81format produced by the command:
82.Sy cksum -m Aq Sy file .
83.Pp
84All
85.Sy SHA512
86files are SHA512 digests for the various files in that directory, in the
87format produced by the command:
88.Sy cksum -a SHA512 Aq Sy file .
89.Pp
90The SHA512 digest is safer, but MD5 checksums are provided so that a wider
91range of operating systems can check the integrity of the release files.
92.Pp
93Files that end in
94.Sy .tgz
95are gzipped tar archives.
96This is used in lieu of
97.Sy .tar.gz
98because the software used to download the sets may incorrectly auto-unpack
99files ending in
100.Sy .gz
101and to accommodate systems which only support 3 character extensions
102to file names.
103.Pp
104All tar archives are relative to the target's
105.Sy /
106directory, and
107.Em do not
108include the leading
109.Dq / .
110.Pp
111The root of the release hierarchy may be the root directory of a
112CD-ROM, but in all other cases it should be
113.Sm off
114.Xo
115.Sy .../NetBSD-
116.Aq Em rel
117.Sy / .
118.Xc
119.Sm on
120.Pp
121The root of the release hierarchy should contain the following
122files and subdirectories:
123.Pp
124.Bl -tag -width "\*[Lt]machine\*[Gt]"
125.It Sy iso/
126CDROM images in ISO 9660 format, usually created with
127.Dq ./build.sh ... iso-image ...

150have an internal layout that corresponds to
151a complete release for a given machine type.
152If built with
153.Dq iso-image-source ,
154then it will also contain a
155.Dq source
156directory.
157These images are usually bootable.
