Works this way in anaconda-18.18.

This is still broken in multiple ways for 2 disks:

a.) By default neither one is checked, which doesn't make sense. Optimized  performance (stripe) is the btrfs default for multiple device volumes.

b.) When I check Redundancy on Root and/or Home, and then click back to the other, Redundancy is unchecked. So the checkbox isn't sticking.

c.) I can choose both options for just two disks, and btrfs raid10 requires 4 disks minimum. The checkboxes don't stick.

Honestly for 2-3 disks, the simpler UI is a radio button, not checkboxes.

For 4+ you could still do radio buttons to support either raid1 or raid0, but not raid10. Or make them checkboxes, if the intent is to support raid10.
