I really like Lennart's work, and this looks like a wonderful project, but does he *really* have to try and slam Ubuntu every chance he gets. (I'm talking about this section:
"Oh, and BTW, as Ubuntu appears to be "focussing" on "clarity" in the "cloud" now ;-), and chose Upstart instead of systemd, this feature won't be available in Ubuntu any time soon. That's (one detail of) the price Ubuntu has to pay for choosing to maintain it's own (largely legacy, such as ConsoleKit) plumbing stack."
That section could have been removed from the article without detracting at all from the information in it. In order for Fedora to "win", Ubuntu does not have to lose.
It's such a shame and it detracts from the technical excellence of what he otherwise does.
