Subject: [PATCH] blscfg: Always look for BLS snippets in the root device
da16a7
da16a7
The blscfg command trying to load the BLS snippets from different devices
da16a7
is a left over from when these where located in the ESP in the EFI case.
da16a7
da16a7
But now that are always located in the /boot directory, the BLS snippets
da16a7
have to be loaded from the root device just like the other files that are
da16a7
in the /boot directory (kernel and initrd images).
da16a7
da16a7
This only worked for legacy BIOS because the boot and root variables were
da16a7
set to the same value. But doesn't work when trying to use a common GRUB
da16a7
config file that could be shared between an EFI and legacy BIOS install.
da16a7
da16a7
That kind of configuration is needed for example on hybrid images that are
da16a7
booted using either EFI or legacy BIOS firmwares.
