This won't survive upgrades properly, so I wouldn't recommend that
approach.  As of Ubuntu 9.10, you should use this pattern instead:

  # update-rc.d dhcp3-server disable

  # update-rc.d dhcp3-server enable

For Upstart jobs, as of Ubuntu 11.04, it's simplest to do:

  # echo manual >/etc/init/name-of-job.override

Before Ubuntu 11.04, the best recourse was to comment out the 'start on'
line in /etc/init/name-of-job.conf, but this was really rather confusing
and error-prone so we improved it.
