Needs to be handled in packaging - anything else is more bloat to the 
binary.

Probably needs to be a real directory as other daemons I've seen use 
this so if a listener is compromised it can't access anything on the 
filesystem.
I've chosen /var/chroot/dhcpcd for mine as that seems to be the flavour 
on NetBSD at least.
