As discussed on opensuse-factory list, running fstrim on btrfs erases
bootloader area, rendering system unbootable. See
https://lists.opensuse.org/opensuse-factory/2016-01/msg00067.html
https://lists.opensuse.org/opensuse-factory/2016-01/msg00090.html
and follow-ups that demonstrate that beginning of device gets zeroed out.
Not sure what we can do, but from GRUB side I can only see disabling
embedding support on btrfs entirely.
