Description of problem: At the end of installation, ifcfg-eth0 contains: NAME=System eth0 This, when sourced by ifup or ifdown, attempts to run the command eth0 after setting NAME=System. Oops :-) AFAICT the only consequence is noise during boot-up or manual ifup/ifdown. Version-Release number of selected component (if applicable): F11-Preview
I'm seeing this too, after a kickstart-based install. I haven't tried doing a non-kickstart-based install to see if the same problem exists there.
Fixed in commit b50a4d2c82f5ebd4df4b898c888b3be750f9f418.
