Bug#411756: not a valid limitation indeed
This limitation went too far - you can't have a *swap* partition as the
first one, but you can have others. So, partman should allow for the
creation of RAID partitions as the first item on a disk.
Further discussion starting at:
Once this is reversed, partman should be patched to prevent people from
using a swap partition as the first thing on the disk. Maybe we should also
have silo-installer error out if it detects the same situation.
