Comment 1 RHEL Program Management 2012-06-12 01:04:26 UTC 
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated in the
current release, Red Hat is unfortunately unable to address this
request at this time. Red Hat invites you to ask your support
representative to propose this request, if appropriate and relevant,
in the next release of Red Hat Enterprise Linux.
Comment 3 Matt Newsome 2013-03-14 12:49:35 UTC 
As Red Hat Enterprise Linux 5 has now entered Production Phase 2, this bug has been re-evaluated with the conclusion that a fix would not be appropriate at this time. Consequently this bug is being closed. Please contact your Red Hat representative if a review is required.
