[Bug 1266200] [NEW] Kubuntu installer should offer btrfs RAID options when presented with two identical mount points

[Chris Samuel]

Public bug reported:

When I was trying to install Kubuntu on my test system I thought I'd try
and see if it would let me configure a RAID-1 btrfs as the root
filesystem from the installer.

So I configured two btrfs filesystems on different devices and set them
both with the same mount point ( / ) hoping that it would consider that
as a clue that I wanted it as RAID (and hopefully RAID-1).

But instead it rejected the option, saying I had to choose a different
mount point name for the second.

It would be *really* nice if the installer could spot you picking the
same mount point for multiple btrfs partitions on different devices and
offer to built the filesystem as btrfs RAID-1 (or RAID-0 if you really
don't like your data).
