The actual difference between the two methods is about system
maintenance --- when your network card burns out (these things happen,
unfortunately), biosdevname allows you to plug a new card into the same
pci slot and just turn the machine back on, with no extra
configuration. If you are configuring udev manually, and tie nic names
to MAC addresses, you are required to reconfigure udev for
the new MAC address of the new card.
The pain is greater in the latter case, while I see no gain at all,
compared to the way of biosdevname.
Maybe the OP can enlighten me *why* does he need MAC-oriented naming
scheme so badly? Just curious... :-)
well, do a restore-probe of a virtual machine backup
usually it get assigend a new MAC and you do not want
get it up ith a IP-collission before you changed
