SYNOPSIS

DESCRIPTION

13       dracut.conf is loaded during the initialisation phase of dracut.
14       Command line parameter will overwrite any values set here.
15
16       *.conf files are read from /usr/lib/dracut/dracut.conf.d and
17       /etc/dracut.conf.d. Files with the same name in /etc/dracut.conf.d will
18       replace files in /usr/lib/dracut/dracut.conf.d. The files are then read
19       in alphanumerical order and will overwrite parameters set in
20       /etc/dracut.conf. Each line specifies an attribute and a value. A #
21       indicates the beginning of a comment; following characters, up to the
22       end of the line are not interpreted.
23
24       dracut command line options will overwrite any values set here.
25
26       Configuration files must have the extension .conf; other extensions are
27       ignored.

52
53       force_drivers+=" <list of kernel modules> "
54           See add_drivers above. But in this case it is ensured that the
55           drivers are tried to be loaded early via modprobe.
56
57       omit_drivers+=" <kernel modules> "
58           Specify a space-separated list of kernel modules not to add to the
59           initramfs. The kernel modules have to be specified without the

118           This can be useful in hostonly mode for resume support when your
119           swap is on LVM an encrypted partition.
120
121       mdadmconf="{yes|no}"
122           Include local /etc/mdadm.conf (default=yes)

131           opportunistic (non-existing tools are ignored).
132
133       nofscks="{yes|no}"
134           If specified, inhibit installation of any fsck tools.

148       acpi_override="{yes|no}"
149           [WARNING] ONLY USE THIS IF YOU KNOW WHAT YOU ARE DOING!
150
151           Override BIOS provided ACPI tables. For further documentation read
152           Documentation/acpi/initrd_table_override.txt in the kernel sources.
153           Search for ACPI table files (must have .aml suffix) in
154           acpi_table_dir= directory (see below) and add them to a separate
155           uncompressed cpio archive. This cpio archive gets glued
156           (concatenated, uncompressed one must be the first one) to the
157           compressed cpio archive. The first, uncompressed cpio archive is
158           for data which the kernel must be able to access very early (and
159           cannot make use of uncompress alogrithms yet) like microcode or
160           ACPI tables (default=no).
161
162       acpi_table_dir="<dir>"
163           Directory to search for ACPI tables if acpi_override= is set to
164           yes.

173           Set logging to syslog level.
174
175       fileloglvl="{0-6}"
176           Set logging to file level.
177
178       logfile="<file>"
179           Path to log file.
180
181       show_modules="{yes|no}"
182           Print the name of the included modules to standard output during
183           build.
184

186           Distribution specific variable mapping. See
187           dracut/modules.d/10i18n/README for a detailed description.

190           The font <fontname> to install, if not specified otherwise. Default
191           is "LatArCyrHeb-16".

FILES

197       /etc/dracut.conf
198           Old configuration file. You better use your own file in
199           /etc/dracut.conf.d/.
200
201       /etc/dracut.conf.d/
202           Any /etc/dracut.conf.d/*.conf file can overwrite the values in
203           /etc/dracut.conf. The configuration files are read in
204           alphanumerical order.
