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 1.10 发布，改进记录：
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)
