As I've understood it, the configuration for DM is userspace and the kernel
can't do any auto detection. This would be a "put off" for me to use as a
root filesystem. Configurations like this (and lvm too last I looked at it)
require an initrd or some other way of setting up the device. Unfortunately
this means that there's configs in 2 locations (one not easily available, if
using initrd. easily != mounting via loop!)
