# NOTE(ianw) : 2021-05-11
# On Fedora there has been a switch to BLS
# https://fedoraproject.org/wiki/Changes/BootLoaderSpecByDefault
# which means that kernel-install will have created entries in
# /boot/loader/entries/...
# and, as the wiki page says
#
# The main issue appears to be that a number of places document
# a way to pass kernel options that is no longer working with
# BLS, i.e. edit /etc/default/grub before running
# grub2-mkconfig.
#
# i.e. exactly what we're doing above to override the root device
# in particular. Override grub2 to use it's old config format and
# remove any BLS entries the kernel install made.
#
# I imagine at some point we will reworking things in a more
# general sense to support BLS if that's what everything is
# switching to.
