Wed Aug 26 10:00:38 CDT 2009 Slackware 13.0 x86_64 is released as stable! Thanks to everyone who helped make this release possible -- see the RELEASE_NOTES for the credits. The ISOs are off to the replicator. This time it will be a 6 CD-ROM 32-bit set and a dual-sided 32-bit/64-bit x86/x86_64 DVD. We're taking pre-orders now at store.slackware.com. Please consider picking up a copy to help support the project. Once again, thanks to the entire Slackware community for all the help testing and fixing things and offering suggestions during this development cycle. As always, have fun and enjoy! -P.

.TH MKINITRD.CONF 5 "05 Februrary 2008" "Slackware 12.1"
|
|
.SH NAME
|
|
.B mkinitrd.conf(5)
|
|
.SH SYNOPSIS
|
|
.B mkinitrd.conf - optional configuration file for
|
|
.I mkinitrd(8)
|
|
|
|
.SH DESCRIPTION
|
|
The
|
|
.I mkinitrd.conf
|
|
file contains options to be passed to
|
|
.I mkinitrd(8)
|
|
on every run if mkinitrd is executed with the -F flag.
|
|
.br
|
|
It is intended as a fast and easy way for the system administrator to
|
|
pass options to mkinitrd without having to type them on each execution.
|
|
|
|
Options passed to
|
|
.I mkinitrd(8)
|
|
on the command line will override any
|
|
values set in the config file.
|
|
|
|
.SH OPTIONS AND SYNTAX
|
|
|
|
All options are in the format of OPTION="value"
|
|
.br
|
|
Unset variables have no effect.
|
|
|
|
.TP 5
|
|
.I SOURCE_TREE
|
|
This is the location for the initrd's source tree.
|
|
.br
|
|
Defaults to "/boot/initrd-tree"
|
|
|
|
.TP 5
|
|
.I CLEAR_TREE
|
|
This option specifies whether to clear the initrd source tree prior to
|
|
creating the initrd.
|
|
.br
|
|
This requires a value of either "0" or "1" where 0=no and 1=yes
|
|
.br
|
|
Examples:
|
|
.br
|
|
CLEAR_TREE="0" # Do not clear initrd tree first
|
|
.br
|
|
CLEAR_TREE="1" # Clear initrd tree first
|
|
|
|
It is recommended to leave this unset and pass "-c" on the command line
|
|
when clearing the tree is desired. Clearing the tree is not desirable
|
|
if you wish to build support for more than one kernel into the initrd
|
|
image.
|
|
|
|
.TP 5
|
|
.I OUTPUT_IMAGE
|
|
This is the location for the initrd image that is created.
|
|
.br
|
|
Defaults to "/boot/initrd.gz"
|
|
|
|
.TP 5
|
|
.I KERNEL_VERSION
|
|
This is the kernel version for which the initrd should be created.
|
|
.br
|
|
Defaults to "$(uname -r)"
|
|
|
|
.TP 5
|
|
.I KEYMAP
|
|
This is the custom keyboard map that should be loaded instead of the
|
|
default 'us' keymap.
|
|
.br
|
|
The file /usr/share/mkinitrd/keymaps.tar.gz contains all possible keymaps
|
|
to choose from (omit the '.bmap' extension in the mkinitrd command)
|
|
.br
|
|
Example: KEYMAP="nl"
|
|
|
|
.TP 5
|
|
.I MODULE_LIST
|
|
This should be a colon-separated list of modules you wish to be included
|
|
in the initrd image.
|
|
.br
|
|
Example: MODULE_LIST="ext3:mbcache:jbd"
|
|
|
|
If you have loadtime options that you need to specify when loading kernel
|
|
modules, those can be added here as well.
|
|
.br
|
|
Example: MODULE_LIST="module1:module2 option=1:module3"
|
|
|
|
.TP 5
|
|
.I LUKSDEV
|
|
When using cryptsetup with an encrypted root partition, use this variable to
|
|
define the *actual* device name of the encrypted root partition and define the
|
|
*mapped* device name as ROOTDEV.
|
|
.br
|
|
For example, if your actual root device name in /etc/fstab is:
|
|
.br
|
|
.I /dev/mapper/cryptroot
|
|
on
|
|
.I /dev/sda2
|
|
|
|
Then you'll need to set:
|
|
.br
|
|
LUKSDEV="/dev/sda2"
|
|
.br
|
|
ROOTDEV="cryptroot"
|
|
|
|
.TP 5
|
|
.I ROOTDEV
|
|
The device on which your root filesystem is located.
|
|
.br
|
|
Example: ROOTDEV="/dev/sda2"
|
|
|
|
If you are using cryptsetup and an encrypted root filesystem, be sure to
|
|
read the option above for LUKSDEV or Bad Things will happen.
|
|
|
|
.TP 5
|
|
.I ROOTFS
|
|
The filesystem type of your root filesystem
|
|
.br
|
|
Example: ROOTFS="ext3"
|
|
|
|
.TP 5
|
|
.I RAID
|
|
This option adds the mdadm binary to the initrd to support RAID.
|
|
Additional modules may be required, depending on your kernel
|
|
configuration. If you wish to add LVM support to the initrd, then
|
|
set this to 1; otherwise, leave it unset or set it to 0.
|
|
.br
|
|
Examples:
|
|
.br
|
|
RAID="0" # Do not add RAID support to initrd
|
|
.br
|
|
RAID="1" # Add RAID support to initrd
|
|
|
|
.TP 5
|
|
.I LVM
|
|
This option adds support for LVM partitions into the initrd.
|
|
If you wish to add LVM support to the initrd, then set this to 1;
|
|
otherwise, leave it unset or set it to 0.
|
|
.br
|
|
Examples:
|
|
.br
|
|
LVM="0" # Do not add LVM support to initrd
|
|
.br
|
|
LVM="1" # Add LVM support to initrd
|
|
|
|
.TP 5
|
|
.I WAIT
|
|
This defines the time to wait, in seconds, until all disks are detected.
|
|
.br
|
|
This is useful for allowing extra time that might be needed for slow usb disks or systems with large amounts of storage to become ready.
|
|
.br
|
|
If not defined, the default is 1 second.
|
|
|
|
.TP 5
|
|
.I RESUMEDEV
