!!NAME


mkinitrd - make an initrd image
!!SYNOPSIS


__mkinitrd__ [[__-k__] [[__-d__ ''confdir'']
[[__-m__ ''command''] [[__-o__ ''outfile'']
[[__-r__ ''root''] ''moduledir''
!!DESCRIPTION


The __mkinitrd__ script constructs a directory structure
that can serve as an __initrd__ root file system. It then
generates an image containing that directory structure using
mkcramfs(8), which can be loaded using the
__initrd__ mechanism. The kernel modules placed in the
directory structure will be taken from ''moduledir''.
This is usually of the form
''/lib/modules/your-kernel-version''.


The directory structure can be customised by placing scripts
into ''confdir/scripts''. They will be run using
run-parts(8) just before the directory is fed to
mkcramfs(8). You can also specify modules to load by
putting them in ''confdir/modules'', whose format is
identical to that of ''/etc/modules'', which is described
in __modules(5)__.


When the system boots using an __initrd__ image created
by mkinitrd(8), the __linuxrc__ will wait for an
amount of time which is configured through
mkinitrd.conf(5), during which it may be interrupted
by pressing __ENTER__. After that, the modules specified
in ''confdir/modules'' (and possibly others if
__ROOT__ is not null) will be loaded, followed by any
actions generated when __ROOT__ is not null. Finally any
scripts or executables in ''/scripts'' will be run in
alphabetical order.
!!OPTIONS


__-d__ ''confdir''


By default __mkinitrd__ looks for its configuration files
in ''/etc/mkinitrd''. Use this option to override
that.


__-k__


Do not delete the temporary working directory that
__mkinitrd__ uses. This is useful for
debugging.


__-m__ ''command''


This option overrides the setting of __MKIMAGE__ in
''mkinitrd.conf''.


__-o__ ''outfile''


This option causes __mkinitrd__ to write the image to
''outfile'' instead of the standard output.


__-r__ ''root''


This option overrides the setting of __ROOT__ in
''mkinitrd.conf''.
!!FILES


''/etc/mkinitrd/exe''


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


''/etc/mkinitrd/files''


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


''/etc/mkinitrd/mkinitrd.conf''


The default configuration file for the script.


''/etc/mkinitrd/modules''


All modules specified in this file will be loaded when the
system boots using the generated image. However, they are
not automatically included on the image. You will either
have to use the appropriate __MODULES__ setting, or copy
them in using a script in
''/etc/mkinitrd/scripts''.


''/etc/mkinitrd/scripts''


Scripts in this directory are run just before the image is
generated from.
