# This Requires is wrong, because the post/postun scripts have a

# But, there is no way to tell rpm or yast to schedule the installation
# of perl-Bootloader before kernel-binary.rpm if both are in the list of
# packages to install/update. Likewise, this is true for mkinitrd.
# A specific version of perl-Bootloader is not required, because the post/postun
