The most basic one is root=_++++_: +----- +-root=/dev/sda2 +----- +- +-Because device node names can change, dependent on the drive ordering, you are +-encouraged to use the filesystem identifier (UUID) or filesystem label (LABEL) +-to specify your root partition: +----- +-root=UUID=19e9dda3-5a38-484d-a9b0-fa6b067d0331 +----- +- +-or +- +----- +-root=LABEL=myrootpartitionlabel +----- +- +-To see all UUIDs or LABELs on your system, do: +----- +-# ls -l /dev/disk/by-uuid +----- +- +-or +- +----- +-# ls -l /dev/disk/by-label +----- +- +-If your root partition is on the network see <>. +- +-=== Keyboard Settings +-If you have to input passwords for encrypted disk volumes, you might want to set +-the keyboard layout and specify a display font. +- +-A typical german kernel command would contain: +----- +-vconsole.font=latarcyrheb-sun16 vconsole.keymap=de-latin1-nodeadkeys locale.LANG=de_DE.UTF-8 +----- +- +-Setting these options can override the setting stored on your system, if you use +-a modern init system, like systemd. +- +-For dracut versions prior to version +008+ the line would look like: +----- +-LANG=de_DE.UTF-8 SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc KEYTABLE=de-latin1-nodeadkeys +----- +- +-=== Blacklisting Kernel Modules +-Sometimes it is required to prevent the automatic kernel module loading of a +-specific kernel module. To do this, just add rd.blacklist=_++++_, with _++++_ not containing the _.ko_ +-suffix, to the kernel command line. For example: +----- +-rd.driver.blacklist=mptsas rd.driver.blacklist=nouveau +----- +- +-The option can be specified multiple times on the kernel command line. +- +-=== Speeding up the Boot Process +-If you want to speed up the boot process, you can specify as much information +-for dracut on the kernel command as possible. For example, you can tell dracut, +-that you root partition is not on a LVM volume or not on a raid partition, or +-that it lives inside a specific crypto LUKS encrypted volume. By default, dracut +-searches everywhere. A typical dracut kernel command line for a plain primary or +-logical partition would contain: +----- +-rd.luks=0 rd.lvm=0 rd.md=0 rd.dm=0 +----- +- +-On systems with dracut version prior to +008+ the line would look like: +----- +-rd_NO_LUKS rd_NO_LVM rd_NO_MD rd_NO_DM +----- +- +-This turns off every automatic assembly of LVM, MD raids, DM raids and crypto LUKS. +- +-Of course, you could also omit the dracut modules in the initramfs creation +-process, but then you would lose the posibility to turn it on on demand. +- +- +-[[Injecting]] +-=== Injecting custom Files +-To add your own files to the initramfs image, you have several possibilities. +- +-The --include option let you specify a source path and a target path. For example +----- +-# dracut --include cmdline-preset /etc/cmdline.d/mycmdline.conf initramfs-cmdline-pre.img +----- +-will create an initramfs image, where the file cmdline-preset will be copied +-inside the initramfs to _/etc/cmdline.d/mycmdline.conf_. --include can only be specified once. +- +- +----- +-# mkdir rd.live.overlay +-# mkdir rd.live.overlay/etc +-# mkdir rd.live.overlay/etc/conf.d +-# mkdir rd.live.overlay/etc/cmdline.d +-# echo "ip=auto" >> rd.live.overlay/etc/cmdline.d/mycmdline.conf +-# echo export FOO=testtest >> rd.live.overlay/etc/conf.d/testvar.conf +-# echo export BAR=testtest >> rd.live.overlay/etc/conf.d/testvar.conf +-# tree rd.live.overlay/ +-rd.live.overlay/ +-└── etc +- ├── cmdline.d +- │   └── mycmdline.conf +- └── conf.d +- └── testvar.conf +- +-# dracut --include rd.live.overlay / initramfs-rd.live.overlay.img +----- +- +-This will put the contents of the rd.live.overlay directory into the root of the +-initramfs image. +- +-The --install option let you specify several files, which will get installed in +-the initramfs image at the same location, as they are present on initramfs +-creation time. +- +- +----- +-# dracut --install 'strace fsck.ext3 ssh' initramfs-dbg.img +----- +- +-This will create an initramfs with the strace, fsck.ext3 and ssh executables, +-together with the libraries needed to start those. The --install option can be +-specified multiple times. +- +- +-[[NetworkBoot]] +-== Network Boot +- +-If your root partition is on a network drive, you have to have the network +-dracut modules installed to create a network aware initramfs image. +- +-On a Red Hat Enterprise Linux or Fedora system, this means, you have to install +-the _dracut-network_ rpm package: +- +- +----- +-# yum install dracut-network +----- +- +-The resulting initramfs image can be served by a boot manager residing on your +-local hard drive or it can be served by a PXE/TFTP server. +- +-How to setup your PXE/TFTP server can be found in the +-http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Storage_Administration_Guide/[Red +-Hat Enterprise Linux Storage Administration Guide]. +- +-If you specify ip=auto on the kernel command line, then dracut asks a dhcp +-server about the ip adress for the machine. The dhcp server can also serve an +-additional root-path, which will set the root device for dracut. With this +-mechanism, you have static configuration on your client machine and a +-centralized boot configuration on your TFTP/DHCP server. If you can't pass a +-kernel command line, then you can inject _/etc/cmdline.d/mycmdline.conf_, with a method described +-in <>. +- +- +- +- +-=== Reducing the Image Size +- +-To reduce the size of the initramfs, you should create it with by ommitting all +-dracut modules, which you know, you don't need to boot the machine. +- +-You can also specify the exact dracut and kernel modules to produce a very tiny +-initramfs image. +- +-For example for a NFS image, you would do: +- +- +----- +-# dracut -m "nfs network base" initramfs-nfs-only.img +----- +- +-Then you would boot from this image with your target machine and reduce the size +-once more by creating it on the target machine with the --host-only option: +- +- +----- +-# dracut -m "nfs network base" --host-only initramfs-nfs-host-only.img +----- +- +-This will reduce the size of the initramfs image significantly. +- +- +- +-=== NFS Root Device +- +-FIXME +- +-=== iSCSI Root Device +- +-FIXME +- +-=== FCoE Root Device +- +-FIXME +- +-== Troubleshooting +- +-If the boot process does not succeed, you have several options to debug the +-situation.

The required steps will depend on how your +-root volume is configured. Common scenarios include: +- +-* A block device (e.g. _/dev/sda7_) +-* A LVM logical volume (e.g. _/dev/VolGroup00/LogVol00_) +-* An encrypted device (e.g. _/dev/mapper/luks-4d5972ea-901c-4584-bd75-1da802417d83_) +-* A network attached device (e.g. netroot=iscsi:@192.168.0.4::3260::iqn.2009-02.org.fedoraproject:for.all) +- +-The exact method for locating and preparing will vary.

All +-modules are located in _/usr/lib/dracut/modules.d_ or in _/modules.d_. +-The most basic dracut module is _99base_. In _99base_ the initial shell script +-init is defined, which gets run by the kernel after initramfs loading. Although +-you can replace init with your own version of _99base_, this is not encouraged. +-Instead you should use, if possible, the hooks of dracut. All hooks, and the +-point of time in which they are executed, are described in <>. +- +-The main script, which creates the initramfs is dracut itsself. It parses all +-arguments and sets up the directory, in which everything is installed. It then +-executes all check, install, installkernel scripts found in the modules, which +-are to be processed. After everything is installed, the install directory is +-archived and compressed to the final initramfs image. All helper functions used +-by check, install and installkernel are found in in the file _dracut-functions_. +-These shell functions are available to all module installer (install, +-installkernel) scripts, without the need to source _dracut-functions_. +- +-A module can check the preconditions for install and installkernel with the +-check script. Also dependencies can be expressed with check. If a module passed +-check, install and installkernel will be called to install all of the necessary +-files for the module. To split between kernel and non-kernel parts of the +-installation, all kernel module related parts have to be in installkernel. All +-other files found in a module directory are module specific and mostly are hook +-scripts and udev rules. +- +- +-[[stages]] +-== Boot Process Stages +- +-dracut modules can insert custom script at various points, to control the boot +-process. +-These hooks are plain directories containing shell scripts ending with ".sh", +-which are sourced by init. +-Common used functions are in _dracut-lib.sh_, which can be sourced by any script. +- +-=== Hook: cmdline +- +-The _cmdline_ hook is a place to insert scripts to parse the kernel command line +-and prepare the later actions, like setting up udev rules and configuration +-files. +- +-In this hook the most important environment variable is defined: root. The +-second one is rootok, which indicates, that a module claimed to be able to parse +-the root defined. So for example, **root=**__iscsi:....__ will be claimed by the +-iscsi dracut module, which then sets rootok. +- +-=== Hook: pre-udev +- +-This hook is executed right after the cmdline hook and a check if root and +-rootok were set. Here modules can take action with the final root, and before +-udev has been run. +- +-=== Start Udev +- +-Now udev is started and the logging for udev is setup. +- +-=== Hook: pre-trigger +- +-In this hook, you can set udev environment variables with **udevadm control +---property=KEY=_value_** or control the further execution of udev with +-udevadm. +- +-=== Trigger Udev +- +-udev is triggered by calling udevadm trigger, which sends add events for all +-devices and subsystems. +- +-=== Main Loop +- +-In the main loop of dracut loops until udev has settled and +-all scripts in _initqueue/finished_ returned true. +-In this loop there are three hooks, where scripts can be inserted +-by calling /sbin/initqueue. +- +-==== Initqueue +- +-This hook gets executed every time a script is inserted here, regardless of the +-udev state. +- +-==== Initqueue settled +- +-This hooks (initqueue/settled) gets executed every time udev has settled. +- +- +-==== Initqueue timeout +- +-This hooks (initqueue/timeout) gets executed, when the main loop counter becomes half of the +-rd.retry counter. +- +-==== Initqueue finished +- +-This hook (initqueue/finished) is called after udev has settled and +-if all scripts herein return 0 the main loop will be ended. +-Abritary scripts can be added here, to loop in the +-initqueue until something happens, which a dracut module wants to wait for. +- +-=== Hook: pre-mount +- +-Before the root device is mounted all scripts in the hook pre-mount are +-executed. In some cases (e.g. NFS) the real root device is already mounted, +-though. +- +-=== Hook: mount +- +-This hook is mainly to mount the real root device. +- +-=== Hook: pre-pivot +- +-This hook is called before cleanup hook, This is a good place for +-actions other than cleanups which need to be called before pivot. +- +-=== Hook: cleanup +- +-This hook is the last hook and is called before init finally switches root to +-the real root device. This is a good place to clean up and kill processes not +-needed anymore. +- +- +-=== Cleanup and switch_root +- +-Init (or systemd) kills all udev processes, cleans up the environment, +-sets up the arguments for the real init process and finally calls switch_root. +-switch_root removes the whole filesystem hierarchy of the initramfs, +-chroot()s to the real root device and calls /sbin/init with the specified arguments. +- +-To ensure all files in the initramfs hierarchy can be removed, all processes +-still running from the initramfs should not have any open file descriptors left. +- +-== Network Infrastructure +- +-FIXME +- +-== Writing a Module +- +-A simple example module is _96insmodpost_, which modprobes a kernel module after +-udev has settled and the basic device drivers have been loaded. +- +-All module installation information is in the file module-setup.sh. +- +-First we create a check() function, which just exits with 0 indicating that this +-module should be included by default. +- +-check(): +----- +-return 0 +----- +- +-The we create the install() function, which installs a cmdline hook with +-priority number 20 called _parse-insmodpost.sh_.
