Commit bfc756f8d86 ("Set blsdir if the BLS directory path isn't one of the
looked up by default") attempted to set blsdir if /boot/loader/entries was
not the real path of the directory containing the BLS snippets. Which may
be the case if for example /boot/loader/entries is in a btrfs subvolume.
But in the case of ostree, /boot/loader is a symlink to the directory with
the entries for the current deployment. So with ostree the blsdir will be
wrongly set, since GRUB is able to follow the symlinks just fine. In fact,
it has to follow the symlink since otherwise GRUB will always use the BLS
files for the deployment that the symlink pointed out when blsdir was set.
So only set blsdir if /boot/loader/entries is in a btrfs or zfs partition.

Commit bfc756f8d86 ("Set blsdir if the BLS directory path isn't one of the
|
|
looked up by default") attempted to set blsdir if /boot/loader/entries was

|
not the real path of the directory containing the BLS snippets. Which may

|
be the case if for example /boot/loader/entries is in a btrfs subvolume.
|
|
|

But in the case of ostree, /boot/loader is a symlink to the directory with
|
|
the entries for the current deployment. So with ostree the blsdir will be
|
|
wrongly set, since GRUB is able to follow the symlinks just fine. In fact,

|
files for the deployment that the symlink pointed out when blsdir was set.
|
|
|

So only set blsdir if /boot/loader/entries is in a btrfs or zfs partition.
