It works mainly well for me but I only use ISC-DHCPd on my networks.
I noticed the problem only once when I was trying to receive a lease
from a satellite gateway which was acting as DHCP server and NAT
firewall. I could fetch new leases with NetBSD and Windows just fine.
My laptop with 6.0 on and the new DHCP code was unable to talk to this
DHCP server giving me the same errors as noticed by kalin at el.net.

Only with certain kind of hw/sf which in my experience were standard
customer router boxes. Unfortunatelly I do not have access to this hw
and cannot help with debugging of the issue.

Sure, as I said, it depends on what DHCPd you're talking to.

Yes, it's pretty irrelevant to the problem and it seems to me like
kalin at el.net knows how to run dhclient.
