  16 Description
  17 -----------
  18 _dracut.conf_ is loaded during the initialisation phase of dracut. Command line
  19 parameter will overwrite any values set here.
  20
  21 _*.conf_ files are read from /usr/lib/dracut/dracut.conf.d and
  22 /etc/dracut.conf.d. Files with the same name in /etc/dracut.conf.d will replace
  23 files in /usr/lib/dracut/dracut.conf.d.
  24 The files are then read in alphanumerical order and will overwrite parameters
  25 set in _/etc/dracut.conf_. Each line specifies an attribute and a value. A '#'
  26 indicates the beginning of a comment; following characters, up to the end of the
  27 line are not interpreted.
  28
  29 dracut command line options will overwrite any values set here.
  30
  31 Configuration files must have the extension .conf; other extensions are ignored.

  87 [WARNING]

 135     Search for ACPI table files (must have .aml suffix) in acpi_table_dir=
 136     directory (see below) and add them to a separate uncompressed cpio
 137     archive. This cpio archive gets glued (concatenated, uncompressed one
 138     must be the first one) to the compressed cpio archive. The first,
 139     uncompressed cpio archive is for data which the kernel must be able
 140     to access very early (and cannot make use of uncompress alogrithms yet)
 141     like microcode or ACPI tables (default=no).
 142
 143 *acpi_table_dir=*"__<dir>__"::

 159     Path to log file.
 160
 161 *show_modules=*"__{yes|no}__"::
 162     Print the name of the included modules to standard output during build.
 163
 164 *i18n_vars="__<variable mapping>__"::
 165     Distribution specific variable mapping.

 167
 168 *i18n_default_font=*"__<fontname>__"::
 169     The font <fontname> to install, if not specified otherwise.

 175 Files
 176 -----
 177 _/etc/dracut.conf_::
 178     Old configuration file. You better use your own file in
 179     _/etc/dracut.conf.d/_.
 180
 181 _/etc/dracut.conf.d/_::
 182     Any _/etc/dracut.conf.d/*.conf_ file can overwrite the values in
 183     _/etc/dracut.conf_. The configuration files are read in alphanumerical
 184     order.
