Subject: output taint information when the rss-counter check trips up.
Date: Mon, 18 Jun 2012 11:48:17 -0400	[thread overview]
Message-ID: <20120618154817.GA7841@redhat.com> (raw)

We've had a couple reports of this happening, and it's tedious having
to spend a round trip asking "did you have 3rd party modules loaded".
