This way should I ever need to rollback ZFS / I can quickly change the vfs.root.mountfrom to /dev/mirror/gm0 and then have a base system living entirely on UFS. If you do it that way you can easily rollback your ZFS / should you need to and then just reboot back to the ZFS / when you're done. Cheers, Dillon
