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.

       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> "
	   Add a space-separated list of 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
	   without the ".ko" suffix.

       add_drivers+=" <kernel modules> "
	   Specify a space-separated list of kernel modules to add to the
	   initramfs. The kernel modules have to be specified without the
	   ".ko" suffix.

       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,
	   separated by :

       install_items+=" <file>[ <file> ...] "
	   Specify additional files to include in the initramfs, separated by
	   spaces.

       do_strip="{yes|no}"
	   Strip binaries in the initramfs (default=yes)

       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

       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"

       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.

	   Include local /etc/mdadm.conf (default=yes)

       lvmconf="{yes|no}"
	   Include local /etc/lvm/lvm.conf (default=yes)

	   the default is: "umount mount /sbin/fsck* xfs_db xfs_check
	   xfs_repair e2fsck jfs_fsck reiserfsck btrfsck". The installation is
	   opportunistic (non-existing tools are ignored).

       nofscks="{yes|no}"
	   If specified, inhibit installation of any fsck tools.

       ro_mnt="{yes|no}"
	   Mount / and /usr read-only by default.

       kernel_cmdline="parameters"
	   Specify default kernel command line parameters

       kernel_only="{yes|no}"
	   Only install kernel drivers and firmware files. (default=no)

       no_kernel="{yes|no}"

       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)

       stdloglvl="{0-6}"
	   Set logging to standard error level.

       sysloglvl="{0-6}"

       fileloglvl="{0-6}"

       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.
