# Kiwi runs this hook chrooted in the build root after create_initrd and
# before the filesystem is synced to the raw disk. All bind mounts from
# the prepare phase are already gone, so anything we rm here actually
# comes out of the final image.
#
# grub2-mkconfig and the rest of the grub2 build tools can NOT be
# touched here — kiwi re-invokes grub2-mkconfig on the mounted disk
# after this hook. That cleanup happens in Makefile.docker instead,
# after kiwi has finished with the raw disk.
