Subject: [PATCH] blscfg: Fallback to search BLS snippets in
|
|
|
8631a2 |
/boot/loader/entries
|
|
|
8631a2 |
|
|
|
8631a2 |
The default path to search the BLS snippets is /loader/entries, this is
|
|
|
8631a2 |
only a correct assumption if $root ($root) is a boot partition but it's
|
|
|
8631a2 |
not true if /boot isn't a mount point.
|
|
|
8631a2 |
|
|
|
8631a2 |
A user can set a blsdir grub environment variable to choose a different
|
|
|
8631a2 |
path, but instead of failing when /boot is a directory inside the root
|
|
|
8631a2 |
partition fallback to search the BLS in /boot/loader/entries to cover
|
|
|
8631a2 |
that case as well.
