The BLS config filenames are guaranteed to be unique, so they can be used as GRUB2 entry id and can also be used to sort the menu entries. Signed-off-by: Javier Martinez Canillas <javierm@redhat.com>

Subject: [PATCH 072/250] Add GRUB_DISABLE_UUID.
|
|
|
|
This will cause "search --fs-uuid --set=root ..." not to be generated by
|
|
grub2-mkconfig, and instead simply attempt to use the grub device name
|
|
as it understands it.

+Normally, @command{grub-mkconfig} will generate menu entries that use
