I don't know about "less consistent", but I always considered it a feature in Linux vs the BSDs or big iron Unix that I could always count on the first network interface being "eth0".
What does 'first' mean? And the same one isn't consistently first.

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.
When you clone a disk, you can't get the ifcfg-eth* and 70-persistant-net-rules from the old machine, or you don't have that info under version control, with all those systems? <snip>
If you insert the card yourself, you obviously know the slot. And you can tell the position from the back just by looking at it. But Centos6 will detect in random order, so knowing the name on one box doesn't help with another. We have to go through contortions plugging on cable in at a time, doing an 'ifconfig up' and checking which interface shows link up. And the people doing that part wish we used more windows instead of Linux.
ifconfig up? Not ethtool eth?
