I applaud the wish to have consistent naming.

I wish to have a consistent name for a given MAC address, and I wish that to be eth0.

There is clearly a mechanism for this, since an upgrade (rather than a clean install) appears to do it.  But it seems to be buried many layers deep in udev spells :-(

OK.  Gizza clue: what would the symlink be, where would one insert it, and what effect would it have ?  Would, for example, ifconfig or ip recognise the new name and show results using it ?  Would one end up with two apparent "interfaces" ?
