Upstart with "stateful re-exec" now in Ubuntu Raring
After a lot of testing, we have today landed Upstart 1.6.1 in Ubuntu Raring with " stateful re-exec " goodness. What this means is that for all future Upstart upgrades, no reboot is required to make use of the newly-installed version: Upstart will restart itself with no interruption to service such that existing jobs will continue to run. Additionally, it means that an upgrade to any of Upstarts dependent libraries (such as libc and libnih ) can also trigger Upstart to restart itself so that it will automatically start using those new library versions whilst maintaining continuity of service. For those of us who dislike downtime and want to remain current, this is known as a "win" ;-)
