A Unified Kernel Image is a single UEFI PE file that combines a UEFI boot stub,
a Linux kernel image, an initrd, and further resources. The uki command will
locate where the uki file is and create a GRUB menu entry to load it.

[@option{--show-non-default}] [@option{--entry} file]
+Load Unified Kernel Image entries into the GRUB menu.
+
+The @option{--path} option overrides the default path to the directory
containing
+the UKI entries. If this option isn't used, the default location is
+/EFI/Linux in the EFI system partition.
+
+The @option{--show-default} option allows the default boot entry to be added
to the
+GRUB menu from the UKI entries.
+
+The @option{--show-non-default} option allows non-default boot entries to be
added to
+the GRUB menu from the UKI entries.
+
+The @option{--entry} option allows specific boot entries to be added to the
GRUB menu
+from the UKI entries.
+
+The @option{--entry}, @option{--show-default}, and @option{--show-non-default}
options
+are used to filter which UKI entries are added to the GRUB menu. If none are
+used, all entries in the default location or the location specified by
@option{--path}
+will be added to the GRUB menu.
