Detailed Description

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.

Feature highlights:

• 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

Last upstream upstart version is 0.6.0 and it's recommended to update to this version. New release fixes a lot of bugs and brings up new dbus interface.

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.

Dependencies

• dbus >= 1.2.15 - needed patch pending in git HEAD branch, waiting for release 1.2.16. Temporarily accessible via http://plautrba.fedorapeople.org/dbus
• init: transfer state across re-exec - https://bugs.launchpad.net/upstart/+bug/348455
• initscripts: changes to support new job format. Also move job definitions to new location.
