You can also use udev on its own to handle this cleanly, without
involving ifrename:

For example:

[0 dkg at squeak ~]$ cat /etc/udev/netinterfaces.rules
KERNEL=="eth*",    SYSFS{address}=="29:19:db:4b:b6:6b",  NAME="3com"
KERNEL=="eth*",    SYSFS{address}=="d7:53:f6:7d:fd:d8",  NAME="wireless"
KERNEL=="eth*",    SYSFS{address}=="f1:c1:a1:27:10:f0",  NAME="wired"
KERNEL=="eth*",    SYSFS{address}=="26:df:48:50:b0:db:86:c5",   NAME="fw"
[0 dkg at squeak ~]$ ls -la /etc/udev/rules.d/010_netinterfaces.rules 
lrwxrwxrwx 1 root root 22 2006-06-05 01:36 /etc/udev/rules.d/010_netinterfaces.rules -> ../netinterfaces.rules
[0 dkg at squeak ~]$
