I've just installed Daedalus rc4 on a system with multiple disk drives. 
Three of them are combined into a btrfs RAID.  (I *think* its RAID 5 or
btrfs' equivalent, don't remember any longer).

I seem to be able to mount the btrfs file system, but I can't find any
btfs-specific tools.  I've been using things like "btrfs"
