NAME

       loader.conf - Configuration file for systemd-boot

SYNOPSIS

       ESP/loader/loader.conf, ESP/loader/loader.conf.d/*.conf

DESCRIPTION

       systemd-boot(7) will read /loader/loader.conf and any files with the ".conf" extension
       under /loader/loader.conf.d/ on the EFI system partition (ESP).

       Each configuration file must consist of an option name, followed by whitespace, and the
       option value.  "#" may be used to start a comment line. Empty and comment lines are
       ignored.

       Boolean arguments may be written as "yes"/"y"/"true"/"1" or "no"/"n"/"false"/"0".

OPTIONS

       The following configuration options are understood:

       default
           A glob pattern to select the default entry. The default entry may be changed in the
           boot menu itself, in which case the name of the selected entry will be stored as an
           EFI variable, overriding this option.

       timeout
           How long the boot menu should be shown before the default entry is booted, in seconds.
           This may be changed in the boot menu itself and will be stored as an EFI variable in
           that case, overriding this option.

           If the timeout is disabled, the default entry will be booted immediately. The menu can
           be shown by pressing and holding a key before systemd-boot is launched.

       console-mode
           This option configures the resolution of the console. Takes a number or one of the
           special values listed below. The following values may be used:

           0
               Standard UEFI 80x25 mode

           1
               80x50 mode, not supported by all devices

           2
               the first non-standard mode provided by the device firmware, if any

           auto
               Pick a suitable mode automatically using heuristics

           max
               Pick the highest-numbered available mode

           keep
               Keep the mode selected by firmware (the default)

       editor
           Takes a boolean argument. Enable (the default) or disable the editor. The editor
           should be disabled if the machine can be accessed by unauthorized persons.

       auto-entries
           Takes a boolean argument. Enable (the default) or disable entries for other boot
           entries found on the boot partition. In particular, this may be useful when loader
           entries are created to show replacement descriptions for those entries.

       auto-firmware
           Takes a boolean argument. Enable (the default) or disable the "Reboot into firmware"
           entry.

EXAMPLE

           # /boot/efi/loader/loader.conf
           timeout 0
           default 01234567890abcdef1234567890abdf0-*
           editor no

       The menu will not be shown by default (the menu can still be shown by pressing and holding
       a key during boot). One of the entries with files with a name starting with
       "01234567890abcdef1234567890abdf0-" will be selected by default. If more than one entry
       matches, the one with the highest priority will be selected (generally the one with the
       highest version number). The editor will be disabled, so it is not possible to alter the
       kernel command line.
