Upstart 是一個用以替換 /sbin/init 守護程式的軟體，基於事件機制開發。可用來處理啟動過程中的任務和服務啟動。
Upstart 1.10 釋出，改進記錄：
- New bridges: upstart-local-bridge and upstart-dconf-bridge.
- A new "reload signal" stanza to allow jobs to specify a custom signal that will be sent to the main process (rather than the default SIGHUP).
- Inclusion of Session Init sample jobs.
- Re-exec fixes for handling chroot sessions.
- A shutdown fix for Session Inits.
- A new Python 3 module and accompanying integration test suite for testing Upstart running as PID 1 and as a Session Init (privileged and non-privileged)
