* Add password option to pass in initial elabman password on the
  command line.

* Call Rob's firstuser script with password to set up the initial
  account and project.

* Startup elvind and apache.

* Run initial named configuration and install named files, then start
  up named.

* Create the initial experiments, now that all the above daemons are
  running.

The basic idea here is that you no longer need to reboot ops or boss
when installing Emulab. Run the ops install, then run the boss
install. Then reboot (ops first of course). This should make the
initial setup synchronization slightly easier, I hope ...
