Правда, они забыли упомянуть, что для запуска Гнома на Опенбсд понадобилось кое-чего отломать, да и сами мейнтейнеры будущего у Гнома в БСД не видят.https://lists.debian.org/debian-devel/2013/10/msg00580.html
On OpenBSD we just dropped the features that need systemd for now. There was some talk about porting some systemd interfaces but the path GNOME is currently taking made us stop for now since it seems clearer each day that systemd will be a hard requirement at some point (not just 'some' interfaces). Even if they do not call it a hard requirement, you will loose 1/2 of what makes GNOME interesting which would render it useless to us.
So for now it works ok enough I would say, but in the middle term, I don't see any future for !linux+systemd in GNOME. While some people are really opened about keeping fallback code for ConsoleKit or portability patches, some don't care at all or are even getting in our way on purpose.
That is my own feeling so far, but it would be interesting to know what other folks think (FreeBSD, Gentoo...).
