hi..

the problem is actually mine, not Marcin's.
there is no dhclient.leases because this is the first time EVER i used it
on the this brand new 6 install.  dhclient.conf is empty as always has
been for me - from 4.x till 5.4. i've never used ISC-DHCPd before. i've
been using dhclient for a while - for wi0 also - after configuring the
essentials with ifconfig (with scripts for different locations and and wep
keys)....  so yes - i know how to use dhclient...

thanks....
