* Comparison of different backends for package installation
* All times are in seconds. All tests ran with warm caches. Longer is worse.
* Data was collected from multiple runs but only one sample of each shown here.
* Accompanying spreadsheet with full data is also available.

The other day, Chef announced an "application automation" system called Habitat. [1] Not too surprisingly, a lot of people have asked for my opinion about it, so I might as well collect some of my thoughts here.

First off, let me say that I like the Chef team and I welcome new projects in this space - especially when they're open source. Most of my early config management work has been with Puppet, but I think that Chef got a lot of things right, and they've also done an amazing job around community and avoiding open core. Nathen Harvey has no doubt been a driving influence here, and he's always been a pleasure to talk to at conferences. It's also worth mentioning that while my recent work on #mgmtconfig [2] has been heavily influenced from my time hacking on Puppet, I've tried to borrow ideas and draw inspiration from Chef concepts when they were more appropriate than what Puppet was doing.

The Habitat project was made public with almost 1800 commits so far. I really wish that if organizations

commit b870395fe3f82eaab7c146d83b3a3f0cab2b63f6
Author: James Shubin <james@shubin.ca>

    Inline image display and storage
    
    This patch adds two forms of inline image storage.
    1) Inline storage of a png file within the python source code. This is
    especially useful so that the user can offer a pretty front end, without
    having to clutter their ~/bin with additional files.
