Aha - this 'ifwatchd_flags="-c somescript.sh -n otherscript.sh' what is in rc.d 
decides,
what connection is active and passes the further configuration things to
the script. In the script I will use ifconfig ipw0, for example.

dhclient=YES from rc.d will stay like that? And it applies for either
interface what ifwatchd dedects? Is this the correct logics?

Thanks!
