grub2/0207-10_linux.in-Merge-logic-from-10_linux_bls-and-drop-t.patch
Javier Martinez Canillas 7509e59c4a
Drop 10_linux_bls and avoid corner case of blsdir set with ostree 
The logic to parse the BLS configs to generate a set of menuentry commands
that's needed on ppc64le machines with bootloaders that don't have support
to parse BLS config directly, was implemented in a 10_linux_bls script.

But there's no need to have a separate script just for this and this logic
can be merged into the 10_linux script to avoid code duplication.

Also since the blscfg module will also now be used by ostree-based distros
there is a possible corner case in which a user set the blsdir variable to
a BLS directory path that is different than the default used by ostree.

So to avoid possible issues, only drop the marker file to specify that the
bootloader has support to parse BLS files if this variable hasn't been set.

Subject: [PATCH] 10_linux.in: Merge logic from 10_linux_bls and drop that
script
There's a 10_linux_bls snippet that's used in ppc64le machines to generate
a set of menuentry commands by parsing BLS configs in /boot/loader/entries.
This was made because on PowerNV ppc64le machines that boot using the OPAL
firmware, there could be an old version of the Petitboot bootloader that
doesn't have support to parse BLS snippets.
But there is no need to have a separate GRUB script for that and the logic
could just be part of the usual 10_linux snippet.
Also the BLS files could be used directly if the bootloader has support to
parse them, which is the case for GRUB that's used in ppc64le OF or if the
Petitboot used in ppc64le OPAL machines is version 1.8.0 or newer.
So only generate the menuentry commands from the BLS snippets in the case
of OPAL machines with an old Petitboot version.
