Hi!
Looks like kernel is broken without the bellow patch.

Please try out the functionality by putting rc_ng=YES into your
rc.conf and post any problems you might have.
I have given this a try, but have a few problems. My rc.conf is attached.
1:
When bringing up fxp0 with IP from DHCP i get:
Doing initial network setup: hostnamefxp0:
flags=8843UP,BROADCAST,RUNNING,SIMPL
EX,MULTICAST mtu 1500
inet 0.0.0.0 netmask 0xff00 broadcast 255.255.255.255
...
Without rc_ng, and a manual 'dhclient fxp0' still works. Is there
another way to do this with this new scheme?
This is solved with the below patch.

sendmail_enable=NONE did'nt help either. This can be fixed with below
patch.
It still complains with
/etc/rc: WARNING: $sendmail_enable is not set properly.
but sendmail is no longer started.
