= Summary = * Added stateful re-exec support such that when Upstart is asked to restart itself using 'telinit u', the new instance of PID 1 will retain knowledge of all system jobs and running instances.
See also: https://wiki.ubuntu.com/FoundationsTeam/Specs/QuantalUpstartStatefulReexec = Code = https://code.launchpad.net/~upstart-devel/upstart/stateful-reexec = Limitations = Known limitations that may impact users: - D-Bus connections Not currently retained across the re-exec. Impact: Affects the bridges - they will be respawned, but there is a small window where events could be lost. Plan: - We have a patch for D-Bus to overcome this limitation which will be upstreamed to the D-Bus mailing list for discussion. - Modify the bridges to auto-reconnect themselves when Upstart re-execs. - Upstart sessions (user jobs and chroots) are not currently handled and are ignored on re-exec. Impact: User jobs and chroot sessions will not be managed post-re-exec. Plan: Serialise ConfSource objects (not required for system jobs). Complete details can be found in 'init/state.h'. = Diff Stats = 48 files changed, 11038 insertions(+), 1156 deletions(-) = Thanks = Thanks to Steve Langasek and Colin Watson for their contributions.
