Subject: [PATCH] BLS files should only be copied by grub-switch-to-blscfg if
BLS isn't set
Currently the grub-switch-to-blscfg script doesn't update the grub.cfg if
GRUB_ENABLE_BLSCFG=true is already set in /etc/default/grub. But it still
copies the BLS files which may overwrite fields modified by the user.
