I agree with what you say entirely - and I would imagine similar work 
would be needed for any DHCP6 client. I have no idea how privsep or 
Capsicum should work under dhcpcd (I have zero knowledge in these areas) 
and would welcome any discussion to move this forwards.

For privsep, would it be enough to open ports, drop privs, read the 
message, validate the message and then send it to the root process? Or 
is there something more expected?
