It runs these checks on the scratch config: _check_device SCRATCH_DEV optional $SCRATCH_DEV if [ ! -z "$SCRATCH_MNT" -a ! -d "$SCRATCH_MNT" ]; then echo "common/config: Error: \$SCRATCH_MNT ($SCRATCH_MNT) is not a directory" exit 1 fi If SCRATCH_DEV/SCRATCH_MNT is not set - which is a valid config - the all that is supposed to happen is that tests which call _require_scratch() should not run. This, in turn should prevent the mkfs->rm problem you mention. The above code in get_next_config() is what needs fixing, not the check code... How did you actually trip over this? I'm guessing you have a config problem where you are defining SCRATCH_DEV but not SCRATCH_MNT? Or you didn't set SCRATCH_DEV_NOT_USED?
