Description
-----------
_dracut.conf_ is loaded during the initialisation phase of dracut. Command line
-parameter will overwrite any values set here.
+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 overwrite parameters
+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 overwrite any values set here.
+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

+
*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 a space-separated list of dracut modules.

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

+ 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)
-*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 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.
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)
+ 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=no)
+ Combine early microcode with ramdisk (default=yes)
*stdloglvl*="__\{0-6\}__"::
Set logging to standard error level.
*show_modules=*"__{yes|no}__"::
Print the name of the included modules to standard output during build.
-*i18n_vars="__<variable mapping>__"::
+*i18n_vars=*"__<variable mapping>__"::
Distribution specific variable mapping.
See dracut/modules.d/10i18n/README for a detailed description.

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>_"::
