Thank you Eugene, this is very informative, I'll have to take
a closer look at this as a solution, but I did not find it when
I was reading the man pages and such. What I see in other implementations
is the ability to supersede or ignore the default route directly
by configuration entires in /etc/dhclient.conf.
Again, thank you,
