Upstart 是一个用以替换 /sbin/init 守护进程的软件，基于事件机制开发。可用来处理启动过程中的任务和服务启动。
Upstart 1.9 发布了，改进记录包括：
Apparmor support was added by means of two new stanzas: 'apparmor load' and 'apparmor switch'.
Stateful re-exec now serialises all objects, not just the minimum set. Inherited environment variables can now be unset for Session Inits.
The ability to specify multiple configuration directories when running as a Session Init was added.
libupstart, a client library for communicating with Upstart, was added along with upstart-dbus-bridge, a new bridge that allow jobs to react to D-Bus signals.
There were also fixes and documentation improvements
