Subject: [PATCH] allow setting additional dracut parameters for DVD s390x
 installs

The installation from DVD on s390x needs setting the target disks and
network information that are usually set by editing the generic.prm file.
By including the "rd.cmdline=ask" parameter dracut will open a simple
dialog so the user can enter the required information.
