Subject: [PATCH] Only attempt to scan different BLS directories on EFI
|

Current BLS support attempted to scan for BLS directories, but this only
|
|
|
8631a2 |
makes sense on EFI, where BLS fragments are in /loader/$vendor/entries.
|
|
|
8631a2 |
|
|
|
8631a2 |
For BIOS, only either the default /loader/entries path should be scanned
|
|
|
8631a2 |
or the BLS directory defined in the blsdir GRUB 2 environment variable.
