Other binaries may be added to the +initrd, and the script is easy to modify. Be creative. :-) + + -F Use the contents of /etc/mkinitrd.conf (optional) + If this is used in conjunction with any other options passed + on the command line, the command-line options will override + the config file options. See mkinitrd.conf(5) for details. + -c Clear the existing initrd tree first + -f Filesystem to use for root partition (must be used with -r) + --help Display this message + -h Device to resume from hibernation. Needs to be the name of + the swap partition holding the hibernation image. + -k Kernel version to use + -l Custom keymap to load. Like, 'nl' or 'de-latin1-nodeadkeys' + -m A colon (:) delimited list of kernel modules to load. + Additional options may be added to use when loading the + kernel modules (but in this case the entire list must be + wrapped with double quotes). Any dependencies of requested + modules will also be added to the initrd. + -o Output image (default /boot/initrd.gz) + -r Root partition device (must be used with -f) + -s Initrd source tree (default /boot/initrd-tree/) + -u Include udev in the initrd + -w Time to wait until all disks are detected + -C A colon (:) delimited list of luks encrypted block devices to be + unlocked by the initrd using cryptsetup. All devices that must + be unlocked in order to access the root filesystem must be + specified. (Use with '-r' parameter). + -T A colon (:) delimited list of luks encrypted block devices to be + passed the "--allow-discards" option when unlocked by the initrd + using cryptsetup. This has the effect of allowing TRIM on SSD drives. + Be sure your SSD supports this feature (correctly) before enabling + it. See fstrim(8) for more information. + -L Add support for LVM partitions + -K Use a USB key (fat-formatted) to unlock the root LUKS volume + The parameter value is filename of a keyfile, as well as the label + (or uuid) of the partition this file is on. This way, you can unlock + your computer automatically if you have a USB stick with your LUKS + key inserted at boot. A passphrase will still be asked if the LUKS + key can not be found. + For example, if your USB thumb drive has a FAT partition with label + "TRAVELSTICK" and the actual keyfile is called "/keys/alien.luks", + then you need to pass: -K LABEL=TRAVELSTICK:/keys/alien.luks + -B Add /sbin/btrfs to enable scanning for a root filesystem that is + part of a Btrfs multi-device filesystem. + -M Add the files in /etc/modprobe.d/ and /lib/modprobe.d/ to the initrd + -P Prepend the output image with the microcode CPIO archive given in arguments. + -R Add support for RAID partitions + -V Display version number + +A simple example: Build an initrd for a reiserfs root partition: + + mkinitrd -c -m reiserfs + +Another example: Build an initrd image using Linux 2.6.35.4-smp kernel +modules for a system with an ext4 root partition on /dev/sdb3: + + mkinitrd -c -k 2.6.35.4-smp -m mbcache:jbd:ext4 -f ext4 -r /dev/sdb3 + +Note that if you are already logged in with /dev/sdb3 as your / +partition, and it is running ext4, this command works just the same: + + mkinitrd -c -m ext4 + +If run without options, mkinitrd will rebuild an initrd image using +the contents of the $SOURCE_TREE directory, or, if that directory +does not exist it will be created and populated, and then mkinitrd +will exit. + +EOF +} + +create_new_source_tree() { + mkdir -p $SOURCE_TREE + # Make sure a kernel module directory exists: + mkdir -p $SOURCE_TREE/lib/modules/${KERNEL_VERSION} + # Add the initrd-tree skeleton: + ( cd $SOURCE_TREE ; tar xzf /usr/share/mkinitrd/initrd-tree.tar.gz ) + # Make sure we have any block devices that might be needed: + + SLOPPY_DEV_LIST=$(cat /proc/partitions) + for device in $SLOPPY_DEV_LIST ; do + if [ !
