# see bug #259303
# this script runs when the kernel gets updated with YaST
# YaST calls rpm always with -U
# -U replaces all packages with the new one
# rpm removes the files from the old packages after the postinstall script ran
# this will double the required space below /boot
# remove the files from the old packages to make room for the new initrd
# rpm may complain about low disk space if /boot/vmlinux does not fit
