I think you are talking about a script that handles a more "dynamic" database
to force renames/softlinks for devices keeping names identical?
I haven't played with mdev yet, but isn't that already in mdev?
Or does mdev require it to be set manually?
Btw, the "keep same devicename" is rather annoying when having to replace the
network card and the network then doesn't come back up...
