Playing around with the Installer and the DASD layout I found the setting to use a LVM based btrfs. This created a partition with ext2 for the /boot/zipl and then created a partition for LVM and btrfs for the root. I then added the rest of the DASD I usually set aside for the LVM and now I have a nice big btrfs with everything minus /boot/zipl . I'll run this in a test environment for awhile so I can learn how to grow the LVM and btrfs as needed,
