SYNOPSIS
--------
-_/etc/dracut.conf_ _/etc/dracut.conf.d/*.conf_
+_/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 override 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 override 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 override any values set here.
+
+Configuration files must have the extension .conf; other extensions are ignored.
+
+*add_dracutmodules+=*" __<dracut modules>__ "::
+ Add a space-separated list of dracut modules to call when building the
+ initramfs. Modules are located in _/usr/lib/dracut/modules.d_.
+
*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_.
+ This option forces dracut to only include the specified dracut modules.
+ In most cases the "add_dracutmodules" option is what you want to use.
*omit_dracutmodules+=*" __<dracut modules>__ "::
- Omit a space-separated list of dracut modules.
-
-*add_dracutmodules+=*" __<dracut modules>__ "::
- Add a space-separated list of dracut modules.
+ Omit a space-separated list of dracut modules to call when building the
+ initramfs. Modules are located in _/usr/lib/dracut/modules.d_.
*drivers+=*" __<kernel modules>__ "::
Specify a space-separated list of kernel modules to exclusively include in
Specify a space-separated list of kernel modules to add to the initramfs.
The kernel modules have to be specified without the ".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.
-*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.
*install_items+=*" __<file>__[ __<file>__ ...] "::
Specify additional files to include in the initramfs, separated by spaces.
+*install_optional_items+=*" __<file>__[ __<file>__ ...] "::
+ Specify additional files to include in the initramfs, separated by spaces,
+ if they exist.
+
+*compress=*"__{bzip2|lzma|xz|gzip|lzo|lz4|zstd|<compressor [args ...]>}__"::
+ Compress the generated initramfs using the passed compression program. If
+ you pass it just the name of a compression program, it will call that
+ program with known-working arguments. If you pass arguments, it will be called
+ with exactly those arguments. Depending on what you pass, this may result in
+ an initramfs that the kernel cannot decompress.
+
*do_strip=*"__{yes|no}__"::
Strip binaries in the initramfs (default=yes)
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 to "yes", 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_.
+If chrooted to another root other than the real root device, use --fstab and
+provide a valid _/etc/fstab_.
====
*use_fstab=*"__{yes|no}__"::
*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__"::
*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 algorithms 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=yes)
+
*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>__"::
+ 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.
+
+*reproducible=*"__{yes|no}__"::
+ Create reproducible images.
+
+*loginstall=*"__<DIR>__"::
+ Log all files installed from the host to _<DIR>_.
+
+*uefi_stub=*"_<FILE>_"::
+ Specifies the UEFI stub loader, which will load the attached kernel, initramfs and
+ kernel command line and boots the kernel. The default is
+ _/lib/systemd/boot/efi/linux<EFI-MACHINE-TYPE-NAME>.efi.stub_
+ or _/usr/lib/gummiboot/linux<EFI-MACHINE-TYPE-NAME>.efi.stub_
+
+*kernel_image=*"_<FILE>_"::
+ Specifies the kernel image, which to include in the UEFI executable. The default is
+ _/lib/modules/<KERNEL-VERSION>/vmlinuz_ or _/boot/vmlinuz-<KERNEL-VERSION>_
