Failover configuration file errors?

[Jason Gerfen]

I am glad you mentioned this to me because I am incorporating some
failover options in web based interface to assist in management of the
dhcpd service and because I am very unfamiliar with the failover
options I will (now that you mentioned some of the values and their
effects) have to research these options further to perhaps place
limitations on the values that can be entered.

But to answer your question, no, that is not what I planned.
