grub2/0095-Add-BLS-support-to-grub-mkconfig.patch
Javier Martinez Canillas 7e98da058f
Cleanup our patchset to reduce the number of patches 
This change reorganizes and cleanups our patches to reduce the patch number
from 314 patches to 187. That's achieved by dropping patches that are later
reverted and squashing fixes for earlier patches that introduced features.

There are no code changes and the diff with upstream is the same before and
after the cleanup. Having fewer patches makes easier to manage the patchset
and also will ease to rebase them on top of the latest grub-2.04 release.

Subject: [PATCH] Add BLS support to grub-mkconfig
GRUB now has BootLoaderSpec support, the user can choose to use this by
setting GRUB_ENABLE_BLSCFG to true in /etc/default/grub. On this setup,
the boot menu entries are not added to the grub.cfg, instead BLS config
files are parsed by blscfg command and the entries created dynamically.
A 10_linux_bls grub.d snippet to generate menu entries from BLS files
is also added that can be used on platforms where the bootloader doesn't
have BLS support and only can parse a normal grub configuration file.
Portions of the 10_linux_bls were taken from the ostree-grub-generator
script that's included in the OSTree project.
Fixes to support multi-devices and generate a BLS section even if no
kernels are found in the boot directory were proposed by Yclept Nemo
and Tom Gundersen respectively.
