Resolves: bz 220643
Doc changes, to explain about using /dev/mapper devices to avoid the udev race
at boot and to help people figure out how to use dasd devices. Also, the
IBM:S/390 devices are again blacklisted by default.

After initial setup, all access to the multipathed storage should go through the
multipath device.
+When a multipath device is mounted at boot time , udev may not create the
