Hi, Let's cut the FUD.

The APIs that GNOME is using from systemd are simple, well designed and well documented D-Bus APIs [1][2][3]. They are implemented by simple binaries separate from the core systemd. Legacy init systems can just re-use them as-is. Also, systemd includes logind, which replaces ConsoleKit with a much better design. > 4. Finally, is there any reason why Gnome/Kde/Xfce wants to add deps related to SystemD ? I don't understand why these desktops want to depend on a specific Sysint.... Old versions of GNOME (and KDE, XFCE, etc) had to have distro-specific code for a bunch of things, such as changing the timezone, the system locale or the hostname. Because these things are in separate places in every distribution for historical reason. So every desktop had to re-implement these things for every distribution, making a lot of duplicated code. The goal is to have a single set of tools using a common D-Bus API that you only have to implement once per distribution and that every desktop can use. > 3.

I expect that in the not so long term, systemd will become an essential user-space component of desktop Linux, just like crond, syslog, dbus, udev or glibc. Sharing that code just makes sense, that allows distributions to focus on their strength instead of having to maintain a nightmare of shell scripts. Sure you can do a Android and write your own crappier version, but that doesn't gain you anything.
