I am trying this
/dev/sde1 /run/btrfs-root btrfs rw,nodev,relatime,space_cache 0 0
it seemed to work
watch for idv the user name it appears in few places and change it to the name you want.
I got it to reboot and at line 103 i was lost and i tried to update and get a gui but it was not talking to the net. i suspect it needed a driver and that is over my head. I am giving up on arch linux just to complicated to install.
by adding btrfs and btrfs_tools to debian i got it sort of working on debian but using older versions of btrfs I may have to try harder to get suse linux to work it seems to be newer.
