Comment 2 Milos Malik 2012-06-06 11:21:19 UTC
On the other hand it works when run_init chkconfig ... is used. Do we have a proper documentation for such a scenario?

Comment 3 Miroslav Grepl 2012-06-06 12:51:07 UTC
We have fixed this one in Fedora.

Comment 4 Daniel Walsh 2012-06-07 15:57:12 UTC
Yes we should back port the fix.

Comment 5 RHEL Program Management 2012-07-10 08:19:10 UTC
This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.

Comment 6 RHEL Program Management 2012-07-11 01:56:35 UTC
This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development.  This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4.

Comment 8 Josh 2012-09-17 12:20:34 UTC
This also affects targeted policy with unconfined removed.
