Patch against RHEL4 inittscripts to fix bridge behavior
Description of problem:
If we configure a bridge to use DHCP, dhclient gets called on the bridge interface before member interfaces have been added to it.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Set up a bridge br0 and configure it to use DHCP
2. Configure physical interface, eth0 as a bridge member.
3. Restart server
No IP address is acquired on br0.
IP address should be acquired on br0.
This can be fixed by applying the attached patch. This has been fixed in Fedora, and may or may not still be an issue in RHEL5 (haven't checked). It should be corrected in both.
This problem is resolved in the next major release of Red Hat Enterprise Linux. Red Hat does not currently plan to provide a resolution for this in a RHEL 4 update for currently deployed systems.
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 changes 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 defects.
