Comment 5 for bug 1637181

Of course, it still means we'd need `Restriction: needs-root` so I'm not sure how much of an advantage that is. I.e. I don't think it really buys you much.

OTOH, since we're releasing each distroseries from a different branch, maybe we just enable `Restriction: needs-root` for the py35 and coverage autopkgtests on the xenial branch and be done with it.
