Yes, but I must remember: ...this file has to be changed... this one...

Thanks, I wasn't aware, that such kind of workaround is possible for today.
But pay attention: wouldn't it be simpler in the way, I proposed? Even all
the config files would look a bit clearer, having entries like:
"external_nic", "internal_interface" instead of just "rtk0" and so on. Yes,
one can live without this - just like without several other things.
Not being kernel developer, I'm unable to estimate amount of work, which
implementing such feature could take. But, if not that much... I can't see
any real "contras" at the moment.
