So this will actually work with the recent changes that stopped forcing
DASD naming onto users to set the device online. All disk devices listed
in /etc/sysconfig/hardware will now be enabled.

I have a small fear that people clone a lot on s390 and hence have
duplicate UUIDs, but certainly not post-install at this point.

I applied and pushed the patch. Thanks!
