Subject: [PATCH] blscfg: Always look for BLS snippets in the root device
|
|
|
80913e |
|
|
|
80913e |
The blscfg command trying to load the BLS snippets from different devices
|
|
|
80913e |
is a left over from when these where located in the ESP in the EFI case.
|
|
|
80913e |
|
|
|
80913e |
But now that are always located in the /boot directory, the BLS snippets
|
|
|
80913e |
have to be loaded from the root device just like the other files that are
|
|
|
80913e |
in the /boot directory (kernel and initrd images).
|
|
|
80913e |
|
|
|
80913e |
This only worked for legacy BIOS because the boot and root variables were
|
|
|
80913e |
set to the same value. But doesn't work when trying to use a common GRUB
|
|
|
80913e |
config file that could be shared between an EFI and legacy BIOS install.
|
|
|
80913e |
|
|
|
80913e |
That kind of configuration is needed for example on hybrid images that are
|
|
|
80913e |
booted using either EFI or legacy BIOS firmwares.
|
