The manpage for iftab recommends against using eth0, eth1 as interface
It is discouraged to try to map interfaces to default interfaces names
such as eth0, wlan0 or ppp0. The kernel use those as the default name
for any new interface, therefore most likely an interface will already
use this name and prevent ifrename to use it. Even if you use takeover,
the interface may already be up in some cases. Not using those name
will allow you to immediately spot unconfigured or new interfaces.
Good names are either totally unique and meaningfull, such as mydsl or
privatehub, or use larger integer, such as eth5 or wlan5. The second
type is usually easier to integrate in various network utilities.
Perhaps the order of the interface discovery, and the use of ifrename in
this way is leading to the inversion.
