> understand why Gnome, a desktop-environment running on top of X, maybe running on top of Linux, should make it self dependent on a Linux-specific component like systemd GNOME doesn't depend on systemd. See for instance a blogpost about it: http://blogs.gnome.org/ovitters/2013/09/25/gnome-and-logindsystemd-thoughts/ http://blogs.gnome.org/ovitters/2013/09/25/gnome-and-loginds.... GNOME wants either logind (systemd) or ConsoleKit (freedesktop.org, unmaintained). Calling people "guilty" is also not very constructive behaviour, IMO. Too emotional while you're already showing lack of knowledge about this subject.
