Thanks Gary.  This is the result of a couple of different issues.

The recipe above is working around the network initscripts lack of DHCP
support (I'll fix that in Fedora).  It's also being careful to not
trigger NetworkManager (hence ip link set em1 up instead of something
like ifconfig em1 0.0.0.0 up).

So, this is a temporary workaround for lack of DHCP support (the
upstream initscripts should fix this, which I'll test and apply to
Fedora's package).

thanks,
