[K12OSN] not turning on DHCP by default

[Jay Pfaffman]

I've been managing networks and Linux for 10 years.  Twice in the past
3 months I've set up a new K12LTSP box and inadvertently had the wrong
Ethernet port plugged in to the network and brought down the
building's network (OK, not the whole network, just anyone who
requested a new IP number via DHCP).

Am I the only dope?  I recognize the importance of having things just
work after the install, but perhaps there's some way to provide some
protection.  I know I'll never make this mistake again, but I said
that last time.
