We were allowing users to delete their default subvolume, which is problematic.
This test is a regression test to make sure we don't let that happen in the
future.  Thanks,

Is it that hard to just do it right the first time?  I'd rather see
it extracted properly... (perhaps with a helper?)

you spelled "couldn't" with and without a ' - while you're at it.  ;)

Maybe umount & mount since that was the originally detected failure
(rather than simply relying on the exit status?)
