I'd like to run our atf-based tests (on netbsd-6) from a script, to hook
into a larger regression test system for other code. I have a few
questions, not answered by the tests(7) man page on the netbsd-6 branch.
I ran tests two ways. Once was a myself, and once as root. The results
were somewhat different. I realize some tests fail sometimes and not
others, and that's just the way it is. But there were a lot more
skipped tests as a non-root user. Diffing from non-root to root, I see
57 skipped rather than 301:

Presumably that explains the 3 additional xfail, although I don't
understand why a resize_ffs test would need privileges.

So my questions are:
1) Are the three failures above failing for everyone? Should they be
marked XFAIL?
2) What is the best-practices recommendation? To run tests as root, or
as a non-root user? tests(7) hints that _test is used, so presumably
running as root drops privileges for tests that don't need it.
3) In general, are the tests thought to be independent of the state of
the underlying system? Is it valid to run the on a machine at
single-user with zero configuration? (Surely, that seems intended, and
is what anita does.) On a multi-user machine with services running?
Is it a bug if the environment matters?
