Subject: [PATCH] grub-probe: Don't skip /dev/mapper/dm-* devices
|
||
|
|
|
||
|
|
This patch ensures that grub-probe will find the root device placed in
|
||
|
|
/dev/mapper/dm-[0-9]+-.* e.g. device named /dev/mapper/dm-0-luks will be
|
||
|
|
found and grub.cfg will be updated properly, enabling the system to boot.
