You probably want the service to start on run levels 2, 3, 4 and 5, after everything else has started; and stop on run level 0, 1 and 6 before anything else stops, in which case, you would issue the following: update-rc.d resque start 98 2 3 4 5 . stop 02 0 1 6 . Alternatively, there is a "defaults" form that does the same thing but is a bit simpler: update-rc.d resque defaults 98 02 The '98' is the start order while the '02' is the stop order, both being values between 00 and 99. So the commands above will ensure that your service starts very late in the sequence (so everything it depends on should already be started) but is stopped very early when the machine shuts down. And don't forget to remove the /etc/rcS.d/S51resque symlink you accidentally created earlier by following the wiki. For some background info, Linux (and any other System V operating system like Sun Solaris) uses run levels to manage what services start and stop during startup and shutdown. Run levels 2, 3, 4 and 5 are the standard multi-user modes and are identical on a default install, 0 is the run level used when shutting down, 1 when in single user mode and 6 when rebooting. More details on debiandadmin [1]. By default, a Ubuntu box will start in run level 2. Run levels 3, 4 and 5 are generally not used but are made available so that you could customise them and have specific services running only in controlled circumstances. For example Solaris used to (and maybe still does) have core services started on run level 2 but added extra services that were considered potentially unsafe in run level 3 (such as the telnet and ftp daemons). By doing this, you could easily start all those services by changing to run level 3 and stop them again by dropping to run level 2.
