How to handle large number of disk devices in "arbitrary" order?

Would you mind patching your copy of setup-storage in order to further debug
this? It should suffice to change line 100 of Parser.pm to

$disk = `readlink -f $candidates[0]` if (scalar(@candidates) == 1);

[was: $disk = $candidates[0] if (scalar(@candidates) == 1);]

It's not too unlikely that we bump into further issues, but at least this should
help us getting there.

Best,
Michael
