OpenBSD 4.0 review
,----[ Quote ]
| I've tried hard to find a significant weak point in this operating
| system, but there just isn't one. Put simply, OpenBSD makes Unix fun
| and interesting. It's the only Unix-like operating system that you
| can build, customize, and update without running into strange
| problems, bugs, and growing pains. Upgrades are done with
| confidence, not trepidation, and once configured, there isn't a
| whole lot of worrying to do.

Another project with a similar mission, as well as joint/reciprocal
contributions (even more aggressive when it comes to firmware).
