They did work with Upstart, did all the work to integrate it with Fedora and RHEL, and have commented that they thought Upstart was very professionally written and reliable. The problem they found after implementing it is that its event based framework is fragile and doesn't solve the right problem. When they started looking around at other systems, such as launchd which runs the BSD-based Mac OS X, the found that using socket activation to allow services to be implicitly ordered automatically without needing admin intervention was a superior paradigm to the event framework that Upstart has. I believe they even looked at what it would take to modify Upstart to do auto-dependency resolution by socket activation and found that it would be too invasive and different and would break compatibility.

You can see the rationale yourself by reading blog entries by the creators or looking at recorded conference presentations on YouTube. systemd wasn't created on a whim, Lennart et. al. thought long and hard about creating N+1 init systems before tackling this problem.

Having a list of such conference and articles would be helpful IMHO, only for documenting the past once for all.

Humm, we did not work on the integration of Upstart into Fedora. Neither Kay nor me should take credit for that work.

My mistake, I misread and assumed.

I have seen recordings of some of your presentations, I'm not sure which one where you mentioned looking at Upstart, and praising its code quality, it may have been Pushing Big Changes at 2012. There are several conference videos on YouTube but I'm not going to re-watch them all just to get proper attribution.

I was skeptical about the Journal until I saw the practical demonstration video from T-DOSE 2012 on YouTube. It might be worthwhile to include links to these various conference videos on your blog in addition to the wonderful "systemd for Administrators" series, maybe the personal presentation will slow the tide of Internet hatemail, so much is lost when your only interaction is the written word.
