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. _dracut.conf.d/*.conf_ files are
-read in alphanumerical order and will overwrite parameters set in
-_/etc/dracut.conf_. Each line specifies an attribute and a value. A '#'
+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_.
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.
-*install_items+=*" __<kernel modules>__ "::
- Specify a space-separated list of files, which are added to the initramfs
- image.
-
*filesystems+=*" __<filesystem names>__ "::
Specify a space-separated list of kernel filesystem modules to exclusively
include in the generic initramfs.
*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.
+*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_.
+If chrooted to another root other than the real root device, use --fstab and
+provide a valid _/etc/fstab_.
====
*use_fstab=*"__{yes|no}__"::
*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)
*nofscks=*"__{yes|no}__"::
If specified, inhibit installation of any fsck tools.
-*ro_mnt*
+*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}"::
+*no_kernel=*"__{yes|no}__"::
Do not install kernel drivers and firmware files (default=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.
Path to log file.
*show_modules=*"__{yes|no}__"::
- Print included module's name to standard output during build.
+ 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>__"::

+ Default is "LatArCyrHeb-16".
+
+*i18n_install_all=*"__{yes|no}__"::
+ Install everything regardless of generic or hostonly mode.
