Subject: [PATCH] 51-dracut-rescue.install: Don't use BLS fragment shipped by
|
|
|
1bf31c |
kernel package
|
|
|
1bf31c |
|
|
|

For the GRUB and zipl bootloaders the BLS fragment that is shipped by the
|
|
|
1bf31c |
kernel package is used, so the same fragment is used for the rescue entry.
|
|
|
1bf31c |
|
|
|
1bf31c |
But there are cases where this BLS fragment is not suitable. For example,
|
|
|
1bf31c |
if the boot directory is on a btrfs subvolume the path in the linux and
|
|
|
1bf31c |
initrd fiels need to be adjusted with the real path. Otherwise GRUB won't
|
|
|
1bf31c |
be able to read them.
|
|
|
1bf31c |
|
|
|
1bf31c |
The GRUB and zipl kernel-install plugins already take care of this before
|
|
|
1bf31c |
installing the BLS fragments, so just copy the installed fragment that has
|
|
|
1bf31c |
the updated paths instead of using the BLS shipped by the kernel package.
