Subject: [PATCH] Add relative path to the kernel and initrds BLS fields if
|
|
needed
|
|
|
|
The static BLS config file shipped with the kernel package assumes that
|
|
the /boot directory is a mount point, and that the kernel and initramfs
|
|
images relative path is to the root of a boot partition.
|
|
|
|
But there are cases in which this isn't true, for example if a user has
|
|
its /boot in a btrfs subvolume or if /boot isn't a mount point at all.
|
|
|
|
So instead of always using the BLS fragment file as distributed by the
|
|
package, check the relative path that GRUB 2 has to use for the images.
