True. I would like to see this (and other non-essential things like
E.G. avahi-autoipd) move to hooks though.
I wonder if the dhclient format is a sensible choice. Is that something
any "standard" programs can work with? It doesn't seem very easy to
parse in shell scripts. Maybe just shell compatible NAME="<val>" strings
would be better?
