Normally you would use netifrc to configure a gateway and static IP address.  
DHCP is a fallback, in case the static IP subnet has changed - e.g. because 
you changed your home router.

If you *are* using dhcpcd to obtain an IP address from the router then 
arguably your don't need netifrc at all, as I explained in my other message 
earlier.

Regarding the messages you see on your main rig Vs the old rig, you can 
compare the two PC's conf.net files for any differences.
