I get a single error from the regression tests in my freshly updated tree:
not ok 305 - There is one privileged superuser - Found 2
Failed test (/home/jaq/src/rt.3.0.C309/lib/RT/Users_Overlay.pm at line
That test is calling WhoHaveRight to find all the superuser users; is it
possible that your recent WhoHaveRight changes may have caused this?
(Currently going back to doublecheck)
