Tell folks that when they switch from isc to dnsmasq, or vice versa, they will have to kill the currentlys running dhcpd or dnsmasq daemon (or something more graceful if they want to dig around in their init.d or whatever to find it) The new one won't start till the old one is dead. Remind them that the almost certainly want to dig around in their init.d or whatever and figure out how to make sure dhcpd or dnsmasq as appropriate starts on boot. -- Drew Einhorn
