# This is a workaround for the grub issue reported upstream with
#  https://bugzilla.redhat.com/show_bug.cgi?id=2032680

# This clears out and recreates the BLS entries from the upstream
# .qcow2 image in /boot/loader/entries with the current machine-id.
# This means that in the bootloader setup, grub2-mkconfig will update
# config options as required.

# All grub2-switch-to-blscfg really does is call "kernel-install" with
# the kernels installed in /lib/modules -- this is another option for
# recreating the BLS entries.  You can also re-install the kernel
# packages to do this.  Another option again would be just to rename
# the exsiting .conf files.

# If this is already set, grub2-switch-to-blscfg will abort
