Subject: [PATCH] Make grub.cfg compatible to old binaries
|
|
|
|
The new added fwsetup test in the topmost menu is always executed
|
|
regardless older grub may not be able to handle and thus trapped in a
|
|
boot loop between grub and fwsetup.
|
|
|
|
This in particular is to make sure a smooth transition if grub is rolled
|
|
back to older release and needs to boot newer snapshots.
|
|
|
|
Also removing dashes in the UUID that every version released in the wild
|
|
can handle.
