These initial common setups are still needed, especially "tmp", even if
it's not used in the test, because it may be used by other common helper
functions. So there's no need to update these initial setups come with
the template from "new" script, for no good reason.

Only the test itself need to be updated, to avoid cd into SCRATCH_MNT.

And can you please come up with a patch that updates overlay/016 only
and fold 018 updates into its original patch and resend? Because 016 has
been committed and pushed to upstream, but 018 is still in my local tree
and pending pushing to upstream.

Sorry about being a bit picky.. and thank you!
