>Description:
        The following does not work:

        cd /somewhere-without-Atffile
        atf-run /usr/tests/foo-bar

        atf-run currently requires to open the Atffile to deduce the test
        suite the tests belong to, so this prevents running a test outside
        of the current subtree.

        Probably just ignore the test suite thing.  The only issue in doing
        this is that we would not load the test-suite specific configuration
        file for this particular run and we could see side-effects.
