Providing an easier interface for natacontrol RAID/other software RAID in the installer could be useful...I might be the only person that needs this specific configuration, but it might be useful to others. I don't trust my disks to not fail...so I wanted EVERYtHING spread across both disks in a mirror with HAMMER atop that.

I'd take a crack at it myself, but I lack the C knowledge.

Issues that still exist from my approach due to installer limitations:
1). None of this is automated
2). Swap is spread across the mirror. (I suppose this could be a useful option to some, but it would certainly have a performance impact)
3). I need to test this beyond 5 minutes in qemu. (Further testing will be done once the box I'll install to is provisioned)
