DRACUT.CONF(5)                      dracut                      DRACUT.CONF(5)

NAME
       dracut.conf - configuration file(s) for dracut
SYNOPSIS
       /etc/dracut.conf /etc/dracut.conf.d/.conf
       /usr/lib/dracut/dracut.conf.d/.conf
DESCRIPTION
       dracut.conf is loaded during the initialisation phase of dracut.
       Command line parameter will overwrite any values set here.
       *.conf files are read from /usr/lib/dracut/dracut.conf.d and
       /etc/dracut.conf.d. Files with the same name in /etc/dracut.conf.d will
       replace files in /usr/lib/dracut/dracut.conf.d. The files are then read
       in alphanumerical order and will overwrite parameters set in
       /etc/dracut.conf. Each line specifies an attribute and a value. A #
       indicates the beginning of a comment; following characters, up to the
       end of the line are not interpreted.
       dracut command line options will overwrite any values set here.
       Configuration files must have the extension .conf; other extensions are
       ignored.
           Warning
           Space-separated lists have to have a leading and trailing space!
       dracutmodules+=" <dracut modules> "
           Specify a space-separated list of dracut modules to call when
           building the initramfs. Modules are located in
           /usr/lib/dracut/modules.d.
       omit_dracutmodules+=" <dracut modules> "
           Omit a space-separated list of dracut modules.
       add_dracutmodules+=" <dracut modules> "

       drivers+=" <kernel modules> "
           Specify a space-separated list of kernel modules to exclusively
           include in the initramfs. The kernel modules have to be specified

           ".ko" suffix.
       force_drivers+=" <list of kernel modules> "
           See add_drivers above. But in this case it is ensured that the
           drivers are tried to be loaded early via modprobe.
       omit_drivers+=" <kernel modules> "
           Specify a space-separated list of kernel modules not to add to the
           initramfs. The kernel modules have to be specified without the
           ".ko" suffix.
       filesystems+=" <filesystem names> "
           Specify a space-separated list of kernel filesystem modules to
           exclusively include in the generic initramfs.
       drivers_dir="<kernel modules directory>"
           Specify the directory, where to look for kernel modules
       fw_dir+=" :<dir>[:<dir> ...] "
           Specify additional directories, where to look for firmwares,

       do_prelink="{yes|no}"
           Prelink binaries in the initramfs (default=yes)
       hostonly="{yes|no}"
           Host-Only mode: Install only what is needed for booting the local
           host instead of a generic host and generate host-specific
           configuration.
       hostonly_cmdline"{yes|no}"
           If set, store the kernel command line arguments needed in the
           initramfs

           directory name found in /dev/disk. E.g. "by-uuid", "by-label"
       tmpdir="<temporary directory>"
           Specify temporary directory to use.
           Warning
           If chrooted to another root other than the real root device, use
           --fstab and provide a valid /etc/fstab.
       use_fstab="{yes|no}"
           Use /etc/fstab instead of /proc/self/mountinfo.
       add_fstab+=" <filename> "
           Add entries of <filename> to the initramfs /etc/fstab.
       add_device+=" <device> "
           Bring up <device> in initramfs, <device> should be the device name.
           This can be useful in hostonly mode for resume support when your
           swap is on LVM an encrypted partition.
       mdadmconf="{yes|no}"
           Include local /etc/mdadm.conf (default=yes)

           opportunistic (non-existing tools are ignored).
       nofscks="{yes|no}"
           If specified, inhibit installation of any fsck tools.

       acpi_override="{yes|no}"
           [WARNING] ONLY USE THIS IF YOU KNOW WHAT YOU ARE DOING!
           Override BIOS provided ACPI tables. For further documentation read
           Documentation/acpi/initrd_table_override.txt in the kernel sources.
           Search for ACPI table files (must have .aml suffix) in
           acpi_table_dir= directory (see below) and add them to a separate
           uncompressed cpio archive. This cpio archive gets glued
           (concatenated, uncompressed one must be the first one) to the
           compressed cpio archive. The first, uncompressed cpio archive is
           for data which the kernel must be able to access very early (and
           cannot make use of uncompress alogrithms yet) like microcode or
           ACPI tables (default=no).
       acpi_table_dir="<dir>"
           Directory to search for ACPI tables if acpi_override= is set to
           yes.
       early_microcode="{yes|no}"
           Combine early microcode with ramdisk (default=no)

           Set logging to standard error level.
       sysloglvl="{0-6}"
           Set logging to syslog level.
       fileloglvl="{0-6}"
           Set logging to file level.
       logfile="<file>"
           Path to log file.
       show_modules="{yes|no}"
           Print the name of the included modules to standard output during
           build.
       *i18n_vars="<variable mapping>"
           Distribution specific variable mapping. See
           dracut/modules.d/10i18n/README for a detailed description.
       i18n_default_font="<fontname>"
           The font <fontname> to install, if not specified otherwise. Default
           is "LatArCyrHeb-16".
       i18n_install_all="{yes|no}"
           Install everything regardless of generic or hostonly mode.
FILES
       /etc/dracut.conf
           Old configuration file. You better use your own file in
           /etc/dracut.conf.d/.
       /etc/dracut.conf.d/
           Any /etc/dracut.conf.d/*.conf file can overwrite the values in
           /etc/dracut.conf. The configuration files are read in
           alphanumerical order.
