Comment 3 Phil Knirsch 2008-08-18 12:23:21 EDT
This request was evaluated by Red Hat Engineering for inclusion in a Red
Hat Enterprise Linux maintenance release.

Red Hat does not currently plan to provide this change in a Red Hat Enterprise
Linux update release for currently deployed products.

With the goal of minimizing risk of change for deployed systems, and in
response to customer and partner requirements, Red Hat takes a conservative
approach when evaluating enhancements for inclusion in maintenance updates
for currently deployed products. The primary objectives of update releases
are to enable new hardware platform support and to resolve critical

However, Red Hat will further review this request for potential inclusion
in future major releases of Red Hat Enterprise Linux.
