It's basically a design flaw in dhcpcd - dhcpcd needs to have loaded the 
interface.
Here's the example from the man page

                   noipv6rs
                   # Don't touch eth3 at all
                   denyinterfaces eth3

                   interface eth0
                   ia_pd 1 eth1/1 eth2/2

                   # Disable automatic address configuration for eth1
                   # eth1 still gets a delegated prefix
                   interface eth1
                   noipv4
                   noipv6

Also, how did dhcpcd launch? Currently it needs to be started without 
any interfaces listed on the command line.
