Hi.

I'm not sure if people are still using arp(8) a lot, but I've been using
this on several boxes for a while (except for the man page changes I
just wrote).

Juts like mixerctl.conf(5) and wsconsctl.conf(5) and their respective
commands if /etc/arp.conf exists, rc will use arp(8) to add entries on
system startup.

Cheers!
