Sort out the elabinelab NTP situation.
Previously, inner servers (ops and fs) would use "boss" as their ntp(date) server, but boss wasn't running an NTP server. Turns out they were not really using boss anyway (except for the initial ntpdate call) because they still had the outer Emulab /etc/ntp.conf file which pointed the servers to ntp1.emulab.net. That would work fine unless the elabinelab was firewalled. Inner nodes would use inner ops which would work, but inner ops might be isolated. Now by default, inner servers and nodes will use inner boss ("ntp1" is redefined in DNS to point there instead of ops). The firewall rules let inner boss talk to "ntp1" on the outside (ops), so this should always work!
