@node GRUB Configuration
@subsection GRUB Configuration
@cindex GRUB
@cindex boot loader
The operating system uses GNU@tie{}GRUB as its boot loader
(@pxref{Overview, overview of GRUB,, grub, GNU GRUB Manual}). It is
configured using @code{grub-configuration} declarations. This data type
is exported by the @code{(gnu system grub)} module, and described below.
@deftp {Data Type} grub-configuration
The type of a GRUB configuration declaration.
@table @asis
@item @code{device}
This is a string denoting the boot device. It must be a device name
understood by the @command{grub-install} command, such as
@code{/dev/sda} or @code{(hd0)} (@pxref{Invoking grub-install,,, grub,
GNU GRUB Manual}).
@item @code{menu-entries} (default: @code{()})
A possibly empty list of @code{menu-entry} objects (see below), denoting
entries to appear in the GRUB boot menu, in addition to the current
system entry and the entry pointing to previous system generations.
@item @code{default-entry} (default: @code{0})
The index of the default boot menu entry. Index 0 is for the current
system's entry.
@item @code{timeout} (default: @code{5})
The number of seconds to wait for keyboard input before booting. Set to
0 to boot immediately, and to -1 to wait indefinitely.
@item @code{theme} (default: @var{%default-theme})
The @code{grub-theme} object describing the theme to use.

Should you want to list additional boot menu entries @i{via} the
@code{menu-entries} field above, you will need to create them with the
@code{menu-entry} form:
@deftp {Data Type} menu-entry
The type of an entry in the GRUB boot menu.
@table @asis
@item @code{label}
The label to show in the menu---e.g., @code{"GNU System"}.
@item @code{linux}
The Linux kernel to boot.
@item @code{linux-arguments} (default: @code{()})
The list of extra Linux kernel command-line arguments---e.g.,
@code{("console=ttyS0")}.
@item @code{initrd}
A G-Expression or string denoting the file name of the initial RAM disk
to use (@pxref{G-Expressions}).
@end table
@end deftp
@c FIXME: Write documentation once it's stable.
Themes are created using the @code{grub-theme} form, which is not
documented yet.
@defvr {Scheme Variable} %default-theme
This is the default GRUB theme used by the operating system, with a
fancy background image displaying the GNU and Guix logos.
