Introduction 1. Hostonly vs Generic 2. Configuration 2.1. Variables 2.2. Setting up mappings 2.3. Additional settings 3. Kernel parameters ~ 0. Introduction i18n module provides internationalization for initramfs at runtime. It is intended to be generic across different GNU/Linux distributions. i18n and keyboard settings are stored in different files among distributions. To deal with it avoiding hardcoding those differences in the installation script we handle it by mappings between variables used by dracut and the ones in the system. Package maintainer is expected to create those for his/her distribution and it's appreciated to share it with us, so we can include it in source package. 1. Hostonly vs Generic If you invoke dracut with '-H' option, i18n module install script will gather variables values from your configuration files using mappings provided in "/etc/dracut.conf.d/<foo>.conf". Those variables will be put in "etc/vconsole.conf" and "etc/locale.conf" files inside initramfs image. Next it will install only declared font, keymaps and so. When building generic image (dracut without '-H' option), install script copies all content of directories: consolefonts, consoletrans, unimaps and keymaps to image. Take into account that's about 4 MiB. 2. Configuration 2.1. Variables The following variables are used by i18n install script and at initramfs runtime: KEYMAP - keyboard translation table loaded by loadkeys KEYTABLE - base name for keyboard translation table; if UNICODE is true, Unicode version will be loaded. Overrides KEYMAP. EXT_KEYMAPS - list of extra keymaps to bo loaded (sep. by space) UNICODE - boolean, indicating UTF-8 mode FONT - console font FONT_MAP - see description of '-m' parameter in setfont manual FONT_UNIMAP - see description of '-u' parameter in setfont manual The following are appended to EXT_KEYMAPS only during build time: UNIKEYMAP GRP_TOGGLE They were used in 10redhat-i18n module, but not sure of its purpose. I'm leaving it in case... The following are taken from the environment: LANG LC_ALL If UNICODE variable is not provided, script indicates if UTF-8 should be used on the basis of LANG value (if it ends with ".utf8" or similar). 2.2. Setting up mappings Mappings between variables listed in 2.1. and the ones spread around your system are set up in /etc/dracut.conf.d/<foo>.conf. You need to assign mappings to i18n_vars. Here's an example: i18n_vars="/etc/conf.d/keymaps:KEYMAP,EXTENDED_KEYMAPS-EXT_KEYMAPS /etc/conf.d/consolefont:CONSOLEFONT-FONT,CONSOLETRANSLATION-FONT_MAP /etc/rc.conf:UNICODE" First we've got name of file in host file system tree. After colon there's mapping: <from>-<to>. If both variables have the same name you can enter just a single, but it's important to specify it! The module will source only variables you've listed. Below there's detailed description in BNF: <list> ::= <element> | <element> " " <list> <element> ::= <conf-file-name> ":" <map-list> <map-list> ::= <mapping> | <mapping> "," <map-list> <mapping> ::= <src-var> "-" <dst-var> | <src-var> We assume no whitespace are allowed between symbols. <conf-file-name> is a file holding <src-var> in your system. <src-var> is a variable holding value of meaning the same as <dst-var>. <dst-var> is a variable which will be set up inside initramfs. If <dst-var> has the same name as <src-var> we can omit <dst-var>. Example: /etc/conf.d/keymaps:KEYMAP,extended_keymaps-EXT_KEYMAPS <list> = /etc/conf.d/keymaps:KEYMAP,extended_keymaps-EXT_KEYMAPS <element> = /etc/conf.d/keymaps:KEYMAP,extended_keymaps-EXT_KEYMAPS <conf-file-name> = /etc/conf.d/keymaps <map-list> = KEYMAP,extended_keymaps-EXT_KEYMAPS <mapping> = KEYMAP <src-var> = KEYMAP <mapping> = extended_keymaps-EXT_KEYMAPS <src-var> = extended_keymaps <dst-var> = EXT_KEYMAPS 2.3. Additional settings If you encounter following error message: "Directories consolefonts, consoletrans, keymaps, unimaps not found.", you can provide path where those directories lie in your system by setting kbddir in configuration file (the same where you put mappings). 3. Kernel parameters If you create generic initramfs you can set up i18n by kernel parameters using variables listed in 2.1. (except of UNIKEYMAP and GRP_TOGGLE) The recommended minimum is: FONT and KEYMAP. modules.d/10i18n/console_init.sh 0000755 00000003114 15076055246 0012413 0 ustar 00 #!/bin/sh [ -n "$DRACUT_SYSTEMD" ] && exit 0 if [ -x $systemdutildir/systemd-vconsole-setup ]; then $systemdutildir/systemd-vconsole-setup "$@" fi [ -e /etc/vconsole.conf ] && . /etc/vconsole.conf DEFAULT_FONT=LatArCyrHeb-16 DEFAULT_KEYMAP=/etc/sysconfig/console/default.kmap set_keyboard() { local param [ "${UNICODE}" = 1 ] && param=-u || param=-a kbd_mode ${param} } set_terminal() { local dev=$1 if [ "${UNICODE}" = 1 ]; then printf '\033%%G' >&7 stty -F ${dev} iutf8 else printf '\033%%@' >&7 stty -F ${dev} -iutf8 fi } set_keymap() { local utf_switch if [ -z "${KEYMAP}" ]; then [ -f "${DEFAULT_KEYMAP}" ] && KEYMAP=${DEFAULT_KEYMAP} fi [ -n "${KEYMAP}" ] || return 1 [ "${UNICODE}" = 1 ] && utf_switch=-u loadkeys -q ${utf_switch} ${KEYMAP} ${EXT_KEYMAPS} } set_font() { local dev=$1; local trans=''; local uni='' [ -z "${FONT}" ] && FONT=${DEFAULT_FONT} [ -n "${FONT_MAP}" ] && trans="-m ${FONT_MAP}" [ -n "${FONT_UNIMAP}" ] && uni="-u ${FONT_UNIMAP}" setfont ${FONT} -C ${dev} ${trans} ${uni} } dev_close() { exec 6>&- exec 7>&- } dev_open() { local dev=$1 exec 6<${dev} && \ exec 7>>${dev} } dev=/dev/${1#/dev/} devname=${dev#/dev/} [ -c "${dev}" ] || { echo "Usage: $0 device" >&2 exit 1 } dev_open ${dev} for fd in 6 7; do if !

The following steps are executed during a shutdown: * systemd switches to the shutdown.target * systemd starts /lib/systemd/system/shutdown.target.wants/dracut-shutdown.service * dracut-shutdown.service executes /usr/lib/dracut/dracut-initramfs-restore which unpacks the initramfs to /run/initramfs * systemd finishes shutdown.target * systemd kills all processes * systemd tries to unmount everything and mounts the remaining read-only * systemd checks, if there is a /run/initramfs/shutdown executable * if yes, it does a pivot_root to /run/initramfs and executes ./shutdown. The old root is then mounted on /oldroot. /usr/lib/dracut/modules.d/99shutdown/shutdown.sh is the shutdown executable. * shutdown will try to umount every /oldroot mount and calls the various shutdown hooks from the dracut modules This ensures, that all devices are disassembled and unmounted cleanly. To debug the shutdown process, you can get a shell in the shutdown procedure by injecting "rd.break=pre-shutdown rd.shell" or "rd.break=shutdown rd.shell". ---- # mkdir -p /run/initramfs/etc/cmdline.d # echo "rd.break=pre-shutdown rd.shell" > /run/initramfs/etc/cmdline.d/debug.conf # touch /run/initramfs/.need_shutdown ---- In case the unpack of the initramfs fails, dracut-shutdown-onfailure.service executes to make sure switch root doesn't happen, since it would result in switching to an incomplete initramfs.

There are defined 6 logging # levels: # - TRACE (6) # The TRACE Level designates finer-grained informational events than the # DEBUG. # - DEBUG (5) # The DEBUG Level designates fine-grained informational events that are most # useful to debug an application. # - INFO (4) # The INFO level designates informational messages that highlight the # progress of the application at coarse-grained level. # - WARN (3) # The WARN level designates potentially harmful situations. # - ERROR (2) # The ERROR level designates error events that might still allow the # application to continue running. # - FATAL (1) # The FATAL level designates very severe error events that will presumably # lead the application to abort. # Descriptions are borrowed from Log4j documentation: # http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/Level.html # # @section usage Usage # # First of all you have to start with dlog_init() function which initializes # required variables. Don't call any other logging function before that one! # If you're ready with this, you can use following functions which corresponds # clearly to levels listed in @ref intro Introduction. Here they are: # - dtrace() # - ddebug() # - dinfo() # - dwarn() # - derror() # - dfatal() # They take all arguments given as a single message to be logged. See dlog() # function for details how it works. Note that you shouldn't use dlog() by # yourself. It's wrapped with above functions. # # @see dlog_init() dlog() # # @section conf Configuration # # Logging is controlled by following global variables: # - @var stdloglvl - logging level to standard error (console output) # - @var sysloglvl - logging level to syslog (by logger command) # - @var fileloglvl - logging level to file # - @var kmsgloglvl - logging level to /dev/kmsg (only for boot-time) # - @var logfile - log file which is used when @var fileloglvl is higher # than 0 # and two global variables: @var maxloglvl and @var syslogfacility which <b>must # not</b> be overwritten. Both are set by dlog_init(). @var maxloglvl holds # maximum logging level of those three and indicates that dlog_init() was run. # @var syslogfacility is set either to 'user' (when building initramfs) or # 'daemon' (when booting). # # Logging level set by the variable means that messages from this logging level # and above (FATAL is the highest) will be shown. Logging levels may be set # independently for each destination (stderr, syslog, file, kmsg). # # @see dlog_init() ## @brief Initializes dracut Logger. # # @retval 1 if something has gone wrong # @retval 0 on success. # # @note This function need to be called before any other from this file. # # If any of the variables is not set, this function set it to default: # - @var stdloglvl = 4 (info) # - @var sysloglvl = 0 (no logging) # - @var fileloglvl is set to 4 when @var logfile is set too, otherwise it's # - @var kmsgloglvl = 0 (no logging) # set to 0 # # @warning Function sets global variables @var maxloglvl and @syslogfacility. # See file doc comment for details. dlog_init() { local __oldumask local ret=0; local errmsg [ -z "$stdloglvl" ] && stdloglvl=4 [ -z "$sysloglvl" ] && sysloglvl=0 [ -z "$kmsgloglvl" ] && kmsgloglvl=0 # Skip initialization if it's already done.

[<initramfs> [<kernel-version>]] Version: $DRACUT_VERSION Creates initial ramdisk images for preloading modules --kver [VERSION] Set kernel version to [VERSION]. -f, --force Overwrite existing initramfs file. -a, --add [LIST] Add a space-separated list of dracut modules. --rebuild Append arguments to those of existing image and rebuild -m, --modules [LIST] Specify a space-separated list of dracut modules to call when building the initramfs. Modules are located in /usr/lib/dracut/modules.d. -o, --omit [LIST] Omit a space-separated list of dracut modules. --force-add [LIST] Force to add a space-separated list of dracut modules to the default set of modules, when -H is specified. -d, --drivers [LIST] Specify a space-separated list of kernel modules to exclusively include in the initramfs. --add-drivers [LIST] Specify a space-separated list of kernel modules to add to the initramfs. --force-drivers [LIST] Specify a space-separated list of kernel modules to add to the initramfs and make sure they are tried to be loaded via modprobe same as passing rd.driver.pre=DRIVER kernel parameter. --omit-drivers [LIST] Specify a space-separated list of kernel modules not to add to the initramfs. --filesystems [LIST] Specify a space-separated list of kernel filesystem modules to exclusively include in the generic initramfs. -k, --kmoddir [DIR] Specify the directory, where to look for kernel modules --fwdir [DIR] Specify additional directories, where to look for firmwares, separated by : --kernel-only Only install kernel drivers and firmware files --no-kernel Do not install kernel drivers and firmware files --print-cmdline Print the kernel command line for the given disk layout --early-microcode Combine early microcode with ramdisk --no-early-microcode Do not combine early microcode with ramdisk --kernel-cmdline [PARAMETERS] Specify default kernel command line parameters --strip Strip binaries in the initramfs --nostrip Do not strip binaries in the initramfs --hardlink Hardlink files in the initramfs --nohardlink Do not hardlink files in the initramfs --prefix [DIR] Prefix initramfs files with [DIR] --noprefix Do not prefix initramfs files --mdadmconf Include local /etc/mdadm.conf --nomdadmconf Do not include local /etc/mdadm.conf --lvmconf Include local /etc/lvm/lvm.conf --nolvmconf Do not include local /etc/lvm/lvm.conf --fscks [LIST] Add a space-separated list of fsck helpers. --nofscks Inhibit installation of any fsck helpers. --ro-mnt Mount / and /usr read-only by default. -h, --help This message --debug Output debug information of the build process --profile Output profile information of the build process -L, --stdlog [0-6] Specify logging level (to standard error) 0 - suppress any messages 1 - only fatal errors 2 - all errors 3 - warnings 4 - info 5 - debug info (here starts lots of output) 6 - trace info (and even more) -v, --verbose Increase verbosity level -q, --quiet Decrease verbosity level -c, --conf [FILE] Specify configuration file to use. Default: /etc/dracut.conf --confdir [DIR] Specify configuration directory to use *.conf files from. Default: /etc/dracut.conf.d --tmpdir [DIR] Temporary directory to be used instead of default /var/tmp. -l, --local Local mode. Use modules from the current working directory instead of the system-wide installed in /usr/lib/dracut/modules.d. Useful when running dracut from a git checkout. -H, --hostonly Host-Only mode: Install only what is needed for booting the local host instead of a generic host. -N, --no-hostonly Disables Host-Only mode --hostonly-mode <mode> Specify the hostonly mode to use. <mode> could be one of "sloppy" or "strict". "sloppy" mode is used by default. In "sloppy" hostonly mode, extra drivers and modules will be installed, so minor hardware change won't make the image unbootable (eg. changed keyboard), and the image is still portable among similar hosts. With "strict" mode enabled, anything not necessary for booting the local host in its current state will not be included, and modules may do some extra job to save more space. Minor change of hardware or environment could make the image unbootable. DO NOT use "strict" mode unless you know what you are doing. --hostonly-cmdline Store kernel command line arguments needed in the initramfs --no-hostonly-cmdline Do not store kernel command line arguments needed in the initramfs --no-hostonly-default-device Do not generate implicit host devices like root, swap, fstab, etc. Use "--mount" or "--add-device" to explicitly add devices as needed. --hostonly-i18n Install only needed keyboard and font files according to the host configuration (default). --no-hostonly-i18n Install all keyboard and font files available. --hostonly-nics [LIST] Only enable listed NICs in the initramfs. --persistent-policy [POLICY] Use [POLICY] to address disks and partitions. POLICY can be any directory name found in /dev/disk. E.g. "by-uuid", "by-label" --fstab Use /etc/fstab to determine the root device. --add-fstab [FILE] Add file to the initramfs fstab --mount "[DEV] [MP] [FSTYPE] [FSOPTS]" Mount device [DEV] on mountpoint [MP] with filesystem [FSTYPE] and options [FSOPTS] in the initramfs --mount "[MP]" Same as above, but [DEV], [FSTYPE] and [FSOPTS] are determined by looking at the current mounts. --add-device "[DEV]" Bring up [DEV] in initramfs -i, --include [SOURCE] [TARGET] Include the files in the SOURCE directory into the Target directory in the final initramfs. If SOURCE is a file, it will be installed to TARGET in the final initramfs. -I, --install [LIST] Install the space separated list of files into the initramfs. --install-optional [LIST] Install the space separated list of files into the initramfs, if they exist. --gzip Compress the generated initramfs using gzip. This will be done by default, unless another compression option or --no-compress is passed. --bzip2 Compress the generated initramfs using bzip2. Make sure your kernel has bzip2 decompression support compiled in, otherwise you will not be able to boot. --lzma Compress the generated initramfs using lzma. Make sure your kernel has lzma support compiled in, otherwise you will not be able to boot. --xz Compress the generated initramfs using xz. Make sure that your kernel has xz support compiled in, otherwise you will not be able to boot. --lzo Compress the generated initramfs using lzop. Make sure that your kernel has lzo support compiled in, otherwise you will not be able to boot. --lz4 Compress the generated initramfs using lz4. Make sure that your kernel has lz4 support compiled in, otherwise you will not be able to boot. --zstd Compress the generated initramfs using Zstandard. Make sure that your kernel has zstd support compiled in, otherwise you will not be able to boot. --compress [COMPRESSION] Compress the generated initramfs with the passed compression program. Make sure your kernel knows how to decompress the generated initramfs, otherwise you will not be able to boot. --no-compress Do not compress the generated initramfs. This will override any other compression options. --list-modules List all available dracut modules. -M, --show-modules Print included module's name to standard output during build. --keep Keep the temporary initramfs for debugging purposes --printsize Print out the module install size --sshkey [SSHKEY] Add ssh key to initramfs (use with ssh-client module) --logfile [FILE] Logfile to use (overrides configuration setting) --reproducible Create reproducible images --no-reproducible Do not create reproducible images --loginstall [DIR] Log all files installed from the host to [DIR] --uefi Create an UEFI executable with the kernel cmdline and kernel combined --uefi-stub [FILE] Use the UEFI stub [FILE] to create an UEFI executable --kernel-image [FILE] Location of the kernel image --regenerate-all Regenerate all initramfs images at the default location for the kernel versions found on the system If [LIST] has multiple arguments, then you have to put these in quotes.
