Having an event driven system gives you so much more freedom, and it's something I sorely miss when working on Linux (RHEL). Thanks for the scenarios you listed - it's sometimes difficult for me to explain the coolness factor of it to someone.

We run some Feisty servers at work and actually had some trouble creating our own jobs. It seemed sometimes upstart would loop a lot trying to start a process, fail and then stop trying. Running the commands manually of course worked. So anyway, long story short we aren't using it for these trouble processes and never could figure out what was going on.The Documentation seemed non-existent on some features of upstart. It annoyed me that Ubuntu server installs used a system where I pulled some of job syntax from the source code.Anyway I hope it has matured a bit since these Feisty installs, looking forward to updating to Hardy.

Upstart is rocking on!

He said he's got tests that cover 97% of the code and the tests compromise more lines of code than upstart does. (iirc) The only reason it wasn't 100% was that because of the nature of upstart being init and running as pid 1 there are some things that were just not testable. This attention to detail and commitment to quality code shows because as of the time of his presentation the defect rate for upstart was phenomenally low (at that time only 1 defect reported).I found it quite inspiring.

One correction: the PID of init is not "typically" 1--rather the PID of init *must* be 1. This is hard-coded into the OS in all kinds of places (in Linux, and probably in other Unixes, too).

Despite the fact that no packages without upstart-support should be included into Ubuntu (version?), the /etc/event.d does not contain anything new. As long as upstart uses the same scripts as SysV-Init does, it behaves the same, right? So after 18 months there is still _no_ advantage in using upstart, which really is a pity. When will the cool boot-goodness actually be put to use? The thing that is still sorely missing is: boot-stuff that actually uses upstart.

As such, "init" will be the first process on your system. /sbin/init is managed now by Upstart, rather than SysVinit. @Filip Andonov- Even though Ubuntu uses Upstart, remember, that it’s 100% backwards compatible with SysVinit.

I am using UBUNTU 7.10 Gutsy Gibbon. Does this mean, that I am using Upstart? Because as far as I can see with PID 0 in my system is a process called init (/sbin/init). What should I do to use Upstart? Hi, Aaron! I am using UBUNTU 7.10 Gutsy Gibbon. Does this mean, that I am using Upstart?
