Projects / upstart


upstart is a replacement for the /sbin/init daemon that handles starting of tasks and services during boot, stopping them during shutdown, and supervising them while the system is running.

      Release Notes: Stops Upstart from indirectly stealing console ownership. Fixes a bug that could result in incorrect output from initctl(8) environment commands. Fixes incorrect variable usage that could result in a crash. Fixes a stateful re-exec issue triggered by invalid jobs. A stateful re-exec fix to serialize the D-Bus session bus. init-checkconf(8) now uses a Session Init and can also be run as root. upstart-socket-bridge(8) now supports IPv6. Allows telinit(8) to work on systems with no D-Bus system bus.
