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 [ !

An initial ramdisk is a very small +set of files that are loaded into RAM and "mounted" (as initramfs doesn't +actually use a filesystem) as the kernel boots (before the main root +filesystem is mounted). The usual reason to use an initrd is because +you need to load kernel modules before mounting the root partition. +Usually these modules are required to support the filesystem used by the +root partition (ext3, reiserfs, xfs), or perhaps the controller that the +hard drive is attached to (SCSI, RAID, etc). Essentially, there are so many +different options available in modern Linux kernels that it isn't practical +to try to ship many different kernels to try to cover everyone's needs. +It's a lot more flexible to ship a generic kernel and a set of kernel +modules for it. +.SH OPTIONS +.TP +.B \-F +Use the contents of /etc/mkinitrd.conf as options to mkinitrd (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. +.br +See mkinitrd.conf(5) for details. +.TP +.B \-c +Clear the existing initrd tree (by default in /boot/initrd-tree/) first. +If this is not done, running mkinitrd will add additional modules to the +existing initrd. +.TP +.B \-f filesystem +Specify the filesystem to use for the root partition. If this isn't given, +mount will usually figure it out. This option must be used together with the +\-r option in order to be beneficial. +.TP +.B \--help +Display a help summary. +.TP +.B \-h hibernate_partition +Specify the swap partition holding the hibernation image. +.TP +.B \-k kernel version +Use kernel modules from the specified kernel version. mkinitrd will look +for them in /lib/modules/(kernel version). +.TP +.B \-l keymap +Load an alternative keyboard mapping. All supported keyboard mappings +can be found in /usr/share/mkinitrd/keymaps.tar.gz +Leave the '.bmap' out when you supply this parameter. E.g. '-l nl' will +add support for dutch keyboard mapping to the initrd. +.TP +.B \-m module list +This is a list of colon-delimited modules to build into the initrd. +Any dependencies of requested modules will also be added to the initrd. +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). +.TP +.B \-o output image +The file to write the initrd to. (default: /boot/initrd.gz) +.TP +.B \-r root partition +Specify the device to be used as the root partition. If this isn't given, the +kernel default will be used (which is usually fine). This option must be used +together with the \-f option in order to be beneficial. +.TP +.B \-s source tree +The directory to use as the source for the initrd. (default: /boot/initrd-tree/) +.TP +.B \-u +Include udev in the initrd. +.TP +.B \-w +The -w option specifies how long to wait in seconds before assuming that all the +drives are spun up and ready to go. +.TP +.B \-C device list +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. e.g. + + -C /dev/sda2:/dev/sda3 + +Each unlocked device will be assigned an automatically generated luks device +name of the form luks<device> where '<device>' will be the basename of the +encrypted device. e.g. + + /dev/mapper/lukssda2 + +As a convenience to users, where -r specifies one of the device names listed +on the -C option it will be automatically adjusted to use the correct luks +device name. i.e. + + "-C /dev/sda2 -r /dev/sda2" and + "-C /dev/sda2 -r /dev/mapper/lukssda2" + +are equivalent. +.br +(Use with '-r' option). +.TP +.B \-K luks_keyfile +When using cryptsetup to encrypt your partition, you can use a keyfile instead +of a passphrase to unlock the LUKS volume. The LUKSKEY variable holds the +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. +.br +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 set: + + -K LABEL=TRAVELSTICK:/keys/alien.luks +.TP +.B \-T device list +A colon (:) delimited list of luks encrypted block devices to be passed the +"--allow-discards" option when unlocked by the initrd using cryptsetup, e.g. + + -T /dev/sda2:/dev/sda4 + +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. +.TP +.B \-P microcode_archive +This option specifies a cpio archive containing updated microcode for your CPU. +CPU manufacturers occasionally release such updates to fix bugs in the microcode +currently embedded in the CPU. The microcode archive will be prepended to the +output initrd, where the kernel will find it for early patching: + + -P /boot/intel-ucode.cpio + +.TP +.B \-B +This option adds the btrfs utility to the initrd so that multi-device filesystems +will be picked up by a scan (/sbin/btrfs device scan). This is needed if the +root filesystem is a Btrfs multi-device filesystem. +.TP +.B \-L +This option adds LVM support to the initrd, if the tools are +available on the system. +.TP +.B \-R +This option adds RAID support to the initrd, if a static mdadm binary is +available on the system. +.TP +.B \-V +Display version information and exit. +.SH EXAMPLES +A simple example: Build an initrd for a reiserfs root partition: + + mkinitrd -c -m reiserfs + +Another example: Build an initrd image using Linux 2.6.33.1 kernel +modules for a system with an ext3 root partition on /dev/sdb3: + + mkinitrd -c -k 2.6.33.1 -m ext3 -f ext3 -r /dev/sdb3 + +An example of a single encrypted partition setup: +.br +As a user convenience, the value for the "-r" option may also be specified as +"/dev/sda2" in this example: + + mkinitrd -c -k 2.6.33.1 \\ + -m ext4:ehci-hcd:uhci-hcd:usbhid \\ + -f ext4 -r /dev/mapper/lukssda2 \\ + -C /dev/sda2 \\ + -l uk + +Finally, A more complex example: +.br +This one is for a LVM Volume Group (rootvg) comprising of two LVM Physical +Volumes, each of which is on a LUKS encrypted partition that will need to be +unlocked before the root filesystem (/dev/rootvg/lvroot) can be accessed. + + mkinitrd -c -k 2.6.29.6 \\ + -m ext4:ehci-hcd:uhci-hcd:usbhid \\ + -f ext4 -r /dev/rootvg/lvroot \\ + -L -C /dev/sda2:/dev/sdb2 \\ + -l uk + +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. These options are handy for building an initrd mostly +by hand. After creating /boot/initrd-tree/, you can add modules and +edit files by hand, and then rerun mkinitrd to create the initrd. + +Once the initrd is created, you'll need to tell your boot loader +to load it. If you boot with LILO, you will need to add an initrd +line to /etc/lilo.conf. Here's a section of lilo.conf that shows +how to set this up: + + # Linux bootable partition config begins + image = /boot/vmlinuz-generic-2.6.33.1 + initrd = /boot/initrd.gz + root = /dev/sda3 + label = Linux26331 + read-only + # Linux bootable partition config ends + +Note that the line "root = /dev/sda3" is not needed if the root device +has been configured in the initrd image. + +Once you've created the initrd and editing /etc/lilo.conf, you will +need to run 'lilo' to write out the changed boot block. The next +time you reboot the initrd should be loaded along with the kernel. + +Have fun! + +.SH SEE ALSO +mkinitrd.conf (5) + +.SH AUTHOR +Patrick J.

boot your computer\&. +.sp +For instance, when booting a kernel that does not have support for your storage or root filesystem built in (such as the Slackware \fIgeneric\fR kernels)\&. +.sp +When you run the script without parameters, it will examine your running system, your current kernel version and will output an example of a \fImkinitrd\fR commandline that you can use to generate an initrd image containing enough driver support to boot the computer\&. +.sp +You can make it more specific: when you add the filename of a kernel as parameter to the script, it will determine the kernel version from that kernel, and also give an example of the lines that you should add to your \fI/etc/lilo\&.conf\fR file\&. +.sp +If you want your initrd image to have a custom name instead of the default \fI/boot/initrd\&.gz\fR you can add it as another parameter to the script, as follows: +.sp +mkinitrd_command_generator\&.sh \-a "\-o \fI/boot/custom\&.gz\fR" +.sp +The arguments to the \fI\-a\fR parameter will be used as additional arguments to the \fImkinitrd\fR command\&. +.sp +If you need additional modules in the initrd image, apart from what the script determines, you can pass then to the script using the \fI\-m\fR parameter as follows: +.sp +mkinitrd_command_generator\&.sh \-m "uhci\-hcd:usbhid:hid:hid\-generic" +.sp +The above example adds support for USB keyboards to the initrd \- you may need that if you have encrypted your root partition and need to enter a passphrase using a USB keyboard\&. +.sp +Instead of copying and pasting the script\(cqs output, you can create an initrd by directly executing the output, like in this example: +.sp +.if n \{\ +.RS 4 +.\} +.nf +$(mkinitrd_command_generator\&.sh \-\-run /boot/vmlinuz\-generic\-4\&.4\&.1) +.fi +.if n \{\ +.RE +.\} +.sp +That used the \fI\-r\fR or \fI\-\-run\fR switch to make the script only write the \fImkinitrd\fR commandline to the terminal\&. +.sp +When you want to add a section for a specific kernel to \fI/etc/lilo\&.conf\fR directly, use the \fI\-l\fR or \fI\-\-lilo\fR switch and use a command like in this example: +.sp +mkinitrd_command_generator\&.sh \-\-lilo /boot/vmlinuz\-generic\-smp\-4\&.4\&.1 >>/etc/lilo\&.conf +.sp +That command will result in the following lines being added to your \fI/etc/lilo\&.conf\fR file (example for my hardware): +.sp +.if n \{\ +.RS 4 +.\} +.nf +\fI# Linux bootable partition config begins\fR +\fI# initrd created with \*(Aqmkinitrd \-c \-k 4\&.4\&.1 \-m mbcache:jbd2:ext4 \-f ext4 \-r /dev/sda7 \-u \-o
