You could configure a service that starts automatically in run level 3
(or 5) whose start() argument forks off (backgrounds) the process you
want to run, prepended by a "sleep 600" statement.

This way the service won't hold up everything else, but your command
won't run until 600 seconds have elapsed.

You could write the sysv init script to have service <servicename> stop
abort, etc...
