What does 'first' mean?

The problem is when you clone a disk and ship it to a location with 'hands-on' support that doesn't know linux to install in a new chassis that will arrive there at the same time. Somehow you have to get someone to put the 4 network cables in the right NICs before anything can connect. With things tied to MAC addresses that you don't know ahead of time, nothing will work. > Now I have to remember which *PCI slot* my Ethernet card is in when I > run "ifconfig" unless I want to dig through the full listing. Yes, but that's something you _can_ know. -- Les Mikesell lesmikesell at gmail.com
