Description Pavel Roskin 2005-05-25 16:06:22 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.7.8) Gecko/20050512 Fedora/1.0.4-2 Firefox/1.0.4

Description of problem:
/etc/sysconfig/network-scripts/ifup-eth would rename an interface if DEVICE and HWADDR are set in /etc/sysconfig/network-scripts/ifcfg-NAME.  However, it will only happen if DEVICE is already occupied by another device with a different MAC address.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Rename /etc/sysconfig/network-scripts/ifcfg-eth0 to /etc/sysconfig/network-scripts/ifcfg-tu0
2. Change DEVICE=eth0 to DEVICE=tu0 in that file.
3. Reboot.

Actual Results:  The interface is down, still called eth0.

Expected Results:  The interface is up under the name tu0.

Additional info:

I believe the scope of the bug is wider that support for custom names.  Suppose a system has eth0 and eth1.  The hardware for eth0 is removed.  The old eth1 becomes eth0.  It needs to be removed to eth1, but it fails because there is no eth1 already in the system.

Patch that fixes the problem

There is no need to check if FOUNDMACADDR is not empty.  In fact, things are
even better if FOUNDMACADDR is empty, because we don't need to care about
another interface occupying the name.

Comment 2 Bill Nottingham 2005-05-25 16:18:22 UTC
What's your /etc/modprobe.conf look like in this case?

Actually, this is what you need, otherwise you'll run back into 131461 and

Will be in 8.11.1-1 and later.

Comment 5 Pavel Roskin 2005-05-26 20:19:56 UTC
Everything is working after "yum upgrade".  Thank you!

As for /etc/modprobe.conf, I'm using a custom solid kernel, so it's probalby
irrelevant.  But just in case, here it is:
