This seems to work. However, this identifies the two disks in the RAID
systems as two different disks (hde and hdg), with identical contents;
it does not identify them as one [mirrored] RAID disk. If I would
continue to install on one of this disks, I assume that this would not
mean that the contents will be mirrored, so I don't think this can be

As far as I can tell from the specs, this seems to be the documented
behaviour, it will not run on only one disk, and once restarted a new
disk must be inserted and the array be rebuilt before it is possible to
