description:
The cleaner is compiled into rump_lfs and executed as a thread.  Pass
in the raw device using the new -J option.  This avoids the use of
getdiskrawname which is not particularly rump safe in this context and
insures that the rump container device is used for cleaning, not the
outer device.
