.SH "NAME"
loader.conf \- Configuration file for systemd\-boot
.SH "SYNOPSIS"
.PP
\fIESP\fR/loader/loader\&.conf,
\fIESP\fR/loader/entries/*\&.conf
.SH "DESCRIPTION"
.PP
\fBsystemd-boot\fR(7)
will read
\fIESP\fR/loader/loader\&.conf
and any files with the
"\&.conf"
extension under
\fIESP\fR/loader/entries/
on the EFI system partition (ESP)\&.
.PP
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\&.
.PP
Boolean arguments may be written as
"yes"/"y"/"true"/"1"
or
"no"/"n"/"false"/"0"\&.
.SH "OPTIONS"
.PP
The following configuration options in
loader\&.conf
are understood:
.PP
default
.RS 4
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\&.
.RE
.PP
timeout
.RS 4
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\&.
.sp
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\&.
.RE
.PP
console\-mode
.RS 4
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:
.PP
0
.RS 4
Standard UEFI 80x25 mode
.RE
.PP
1
.RS 4
80x50 mode, not supported by all devices
.RE
.PP
2
.RS 4
the first non\-standard mode provided by the device firmware, if any
.RE
.PP
auto
.RS 4
Pick a suitable mode automatically using heuristics
.RE
.PP
max
.RS 4
Pick the highest\-numbered available mode
.RE
.PP
keep
.RS 4
Keep the mode selected by firmware (the default)
.RE
.RE
.PP
editor
.RS 4
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\&.
.RE
.PP
auto\-entries
.RS 4
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\&.
.RE
.PP
auto\-firmware
.RS 4
Takes a boolean argument\&. Enable (the default) or disable the "Reboot into firmware" entry\&.
.RE
.SH "EXAMPLE"
.sp
.if n \{\
.RS 4
.\}
.nf
# /boot/efi/loader/loader\&.conf
timeout 0
default 01234567890abcdef1234567890abdf0\-*
editor no
.fi
.if n \{\
.RE
.\}
.PP
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\&.
