NetBSD/tests/fs/puffs/t_psshfs.sh
jmmv e834f57d5e Properly mark some test cases as having a cleanup routine. Stupidity of
the API?  Most likely; will revise it.

Fixes atf-run breaking when running t_psshfs.  This does not resolve the
underlying issue though, which is atf-run getting confused trying to
unmount the temporary mount point by itself (I think).  (I'm now wondering
if atf should be bothering about unmounting stuff at all.  Maybe not. It is
a tricky and uncommon thing.)
