Hello, Sorry, I promise to not send an email everytime there is an update, this is just particularly important. If you are using an -rc2 or later kernel (which is currently whats in rawhide) you must use the btrfs-progs-0.18 package if you want to use btrfsctl, so doing snapshots or anything like that. You can still format/mount etc with the old btrfs-progs, its just there was a change to the ioctl's so any of the on the fly stuff won't work.
