Upstart is an event-based replacement for the /sbin/init daemon which handles starting of tasks and services during boot, stopping them during shutdown and supervising them while the system is running.
- Tasks and Services are started and stopped by events;
- Events are generated as tasks and services are started and stopped;
- Events may be received from any other process on the system;
- Services may be respawned if they die unexpectedly;
- Supervision and respawning of daemons which separate from their parent process;
- Communication with the init daemon over D-Bus.
Benefit to Fedora
The latest upstream Upstart version is 0.6.0 and upstream is pushing to have all the major distros move to the 0.6 series. The new release fixes a lot of bugs, strengthens some of the code patterns against future bugs, and introduces a job format that will continue to be supported through 1.0.
How To Test
- Bring each upstart job up and down and verify that the job is started and cleaned up correctly and that initctl list reflects its state.
- Move from runlevel s to 1, 3, and 5 and back again and verify that the system ends up in the correct state each time.
- Re-exec init and verify that jobs that were running stay running according to initctl list.
Possibly some changes in command interfaces like initctl, but for most users noticing the change would be a Bad Thing.
