# 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

You are running on a 64kb PAGE_SIZE kernel. The default kernel
switched to 4kb PAGE_SIZE which will prevent it from mounting btrfs
or the swap partition.
To ensure that your system still works, I am refusing to install
this kernel. If you want to force installation regardlesss, reinstall
with the environment variable FORCE_4K set to 1.
To stay with a 64kb PAGE_SIZE kernel, please follow these steps:
$ zypper in kernel-64kb
[ reboot into the new kernel ]
$ zypper rm kernel-default
You will then be on the 64kb PAGE_SIZE kernel and can update your
system normally.
