old ifcfg-eth0

Removing the last three lines "fixed" the problem, but it's still a regression
from RHEL4.
Comment 3 Bill Nottingham 2006-12-06 15:29:17 EST
This is done in dhclient-script (*yuk*).
Comment 4 RHEL Product and Program Management 2007-07-23 11:38:36 EDT
This bugzilla has Keywords: Regression.  

Since no regressions are allowed between releases, 
it is also being proposed as a blocker for this release.  

Please resolve ASAP.

What's the proposed solution here?  Is dhclient-script being changed to honor
Comment 6 David Cantrell 2008-01-07 13:48:56 EST
This this isn't happening in dhclient-script, it happens in anaconda.  On
upgrade, we're preserving everything in the existing ifcfg-ethX file, which
shouldn't be happening.  Attached is a patch to fix the problem.

Upgrade from RHEL4.6 AS to RHEL5.2-Server-20080206.nightly according to 
scenario in comment 0 works as expected.
