Bug 641513

If I uninstall cifs-utils, it does not clean up /lib/mkinitrd/setup/
symlink which is causing mkinitrd to fail to create initrd which in
turn results in unbootable system after update.

This particular bug might be in cifs-utils.rpm (to not call mkinitrd
setup or so), but mkinitrd should survive dangling symlinks and create
the initrd anyways.

bash# rpm -e cifs-utils

bash# zypper patch

Warning: One of installed patches requires reboot of your machine. Reboot as soon as possible.


Now, this is very wrong, /boot/initrd points to initrd-2.6.34.7-0.3-default
which does not exists and therefore rebooting renders the server unusable.
/lib/mkinitrd/setup/81-cifs.sh points to ../scripts/setup-cifs.sh, which
does not exists any more.

Surprisingly, running mkinitrd now creates the initrd just fine:
