OK,
At this point I'm about to go on break, so I'm not confidident pulling the code into trunk rigth now, but I believe the branch at
lp:~smoser/curtin/trunk.lp1523779 represents fixed curtin for this issue.

There are still basically 2 MAAS issues that will block this though:
 a.) maas will need to not send entries for both backing disks of a multipath disk. (bug 1526542).
 b.) maas will need to learn that power systems need a PrEP partition and also that they should use GPT.

Curtin does still have a bug if using MBR and storage config, that it will not understand or act 'flag: prep' in msdos mode.

any powerNV system likely needs both 'a' and 'b' (as I believe they have multipath almost by default).
a KVM guest (powerKVM or kvm on ubuntu) or a powerVM is not likely to see mutipath, so 'b' is probably only necessary.

I believe that powerVM is what Newell was testing with.
