I think this can be done with a pretty simple change to
_check_scratch_fs. i.e. pass the device to be checked in as a
parameter, and if the parameter is not set, have _check_scratch_fs
default to using $SCRATCH_DEV. It's a one-line change to 311, and
about 10 lines of (simple) change to _check_scratch_fs....

Cheers,

Dave.
