Set re-IPL device before reboot on s390x
At the end of installation, set the re-ipl device if the user installed to
a DASD device. Determine where /boot lives and set the re-ipl device to
that, then run shutdown -r. On s390x, this means that clicking the Reboot
button at the end of installation means you will reboot the VM. It only
works for DASD targets right now and not zFCP.
Patch from Brad Hinson <bhinson AT redhat DOT com> and
Jan Glauber <jang AT de DOT ibm DOT com>
