Take a look at:
https://bugzilla.redhat.com/show_bug.cgi?id=188314

I actually used this when going from F10 to F11 as I also wanted to change
my disk partition layout without having to restore everything from backup.
Since then the text based install stuff changed, so the changes needed might
be a little different. Also I was messing with raid 1, not raid 10, so there
will be some other differences.
And if you want you can add a comment. It's doubtful we'll change Jeremy's
opinion, but you never know. I'd like to at least be able to install on
complete arrays, even for configurations that anaconda won't create.
