14 mkinitrd - make an initrd image
15 !!SYNOPSIS
16
17
18 __mkinitrd__ [[__-k__] [[__-d__ ''confdir'']
19 [[__-m__ ''command''] [[__-o__ ''outfile'']
20 [[__-r__ ''root''] ''moduledir''
21 !!DESCRIPTION
22
23
24 The __mkinitrd__ script constructs a directory structure
25 that can serve as an __initrd__ root file system. It then
26 generates an image containing that directory structure using
27 mkcramfs(8), which can be loaded using the
28 __initrd__ mechanism. The kernel modules placed in the
29 directory structure will be taken from ''moduledir''.
30 This is usually of the form
31 ''/lib/modules/your-kernel-version''.
32
33
34 The directory structure can be customised by placing scripts
35 into ''confdir/scripts''. They will be run using
4 perry 36 run-parts(8) just before the directory is fed to
1 perry 37 mkcramfs(8). You can also specify modules to load by
38 putting them in ''confdir/modules'', whose format is
39 identical to that of ''/etc/modules'', which is described
40 in __modules(5)__.
41
42
43 When the system boots using an __initrd__ image created
44 by mkinitrd(8), the __linuxrc__ will wait for an
45 amount of time which is configured through
4 perry 46 mkinitrd.conf(5), during which it may be interrupted
1 perry 47 by pressing __ENTER__. After that, the modules specified
48 in ''confdir/modules'' (and possibly others if
49 __ROOT__ is not null) will be loaded, followed by any
50 actions generated when __ROOT__ is not null. Finally any
51 scripts or executables in ''/scripts'' will be run in
52 alphabetical order.
53 !!OPTIONS
54
55
56 __-d__ ''confdir''
57
58
59 By default __mkinitrd__ looks for its configuration files
60 in ''/etc/mkinitrd''. Use this option to override
61 that.
62
63
64 __-k__
65
66
67 Do not delete the temporary working directory that
68 __mkinitrd__ uses. This is useful for
69 debugging.
70
71
72 __-m__ ''command''
73
74
75 This option overrides the setting of __MKIMAGE__ in
76 ''mkinitrd.conf''.
77
78
79 __-o__ ''outfile''
80
81
82 This option causes __mkinitrd__ to write the image to
83 ''outfile'' instead of the standard output.
84
85
86 __-r__ ''root''
87
88
89 This option overrides the setting of __ROOT__ in
90 ''mkinitrd.conf''.

96
97 This file contains full paths to shared executables that
98 should be included in the __initrd__ image.
99 __mkinitrd__ will include them as well as any shared
100 libraries that they are linked with.

106 This file contains full paths to files that should be
107 included in the __initrd__ image.

109
110 ''/etc/mkinitrd/mkinitrd.conf''

112
113 The default configuration file for the script.
114
115
116 ''/etc/mkinitrd/modules''
117
118
119 All modules specified in this file will be loaded when the
120 system boots using the generated image. However, they are
121 not automatically included on the image. You will either
122 have to use the appropriate __MODULES__ setting, or copy
123 them in using a script in
124 ''/etc/mkinitrd/scripts''.
125
126
127 ''/etc/mkinitrd/scripts''
128
129
130 Scripts in this directory are run just before the image is
131 generated from.
