Good geekie stuff and an alternative work-around.


I have a number of systems with multiple NICs and... I just juggle the 
ethX designations as appropriate. The only interface naming dependencies 
are in the ifcfg configs and Shorewall. Everything else should be 
referring to whatever IP interface address. (Otherwise, your system 
shouldn't be that complicated...)

The only hiccup I've hit was when changing some 100Mb/s NICs to 1Gb/s 
NICs. The kernel found them in reverse order to that before!
