Comment 2 Miloslav Trmač 2013-11-18 18:39:13 EST
Thanks for your report.

No additional option is needed, because tmpwatch never traverses to a different filesystem already by default.  The problem you have encountered happened because a bind mount is not treated as a "different filesystem" in the RHEL 5 and RHEL 6 versions of tmpwatch.

If you are a Red Hat customer with an active subscription, please report the problem using the Red Hat Customer Portal at http://access.redhat.com/ for correct prioritization of the issue.
