mkinitrd.conf - configuration file for mkinitrd

The behaviour of mkinitrd(8) may be altered by changing this file. This file is meant to be parsed as a shell script thus the syntactical rules of a shell script will apply. See sh(1) for more details.

MODULES

The legal values are all, most, dep and none. All modules are included on the image if it is set to all. Setting it to most will cause mkinitrd(8) to exclude modules which are considered unlikely to be necessary in the process of bringing up a root file system. Setting it to dep will cause mkinitrd(8) to use modprobe(8) to calculate exactly what modules are needed. Setting it to none will cause mkinitrd(8) to not include any modules, even if modules were specified in /etc/mkinitrd/modules.

DELAY

The number of seconds the linuxrc script should wait to allow the user to interrupt it before the system is brought up.

ROOT

If this is set to probe, mkinitrd(8) will try to determine the modules needed to bring up the root file system using /etc/fstab. It will also insert code onto the image in order to setup a software RAID device if necessary. This can be disabled by setting it to a null string. If you get the error ``Unknown root device'' then this setting must be disabled and you will need to set up the initrd image manually.

If you wish to use an alternative root device, you can specify it here and mkinitrd(8) will use that to figure out what is needed. You can also set the file system type of your root device by appending it to the value of ROOT with a space in between. You will need to quote the entire value as otherwise the shell will interpret the file system type as a command.

This variable replaces the obsolete PROBE variable. The values probe and the null string correspond to the values on and off for PROBE.

UMASK

The umask is used during the construction of the directory structure and the final image.

MKIMAGE

This should be a command that produces an initrd image given a directory. It must contain two occurrences of %s. The first one will be replaced by the path to the directory for the candidate image. The other one will be replaced by the name of the output file. This can be used to produce images of types other than CRAMFS. For example, to generate ROMFS images, set MKIMAGE to 'genromfs -d %s -f %s'.

BUSYBOX

If this is set to yes then busybox(1) will be included on the initrd image.

PKGSCRIPTS

If this is set to yes then the scripts under /usr/share/initrd-tools/scripts will be run when the initrd image is made.

INITRD_LD_LIBRARY_PATH

This value will be assigned to LD_LIBRARY_PATH when mkinitrd determines the library dependencies of binaries that will be copied onto the image.

RESUME

If this is set, default to this partition to use for resuming. The resume= passed on the command line will override this setting. The kernel needs to have the power management (PM) config's enabled.

RESUME

If this is set, default to this partition to use for resuming. The resume= passed on the command line will override this setting.
