Question: Is systemd on or off topic here ?

From the wiki page - <https://wiki.ubuntu.com/systemd#Warning.21_Experimental_code>

I would think 15.04 is ubuntu +1 and thus off topic as per the FAQ.

We getting tons of questions on this topic , see

[Unable to boot after installing systemd-services and changing the init parameter on boot](https://askubuntu.com/questions/565301/unable-to-install-systemd-on-ubuntu-14-04)

And there is even 

[How can I replace upstart with systemd?](https://askubuntu.com/questions/420917/how-can-i-replace-upstart-with-systemd)

Answer: 
I have *no idea* why they say that systemd is "Experimental code" when is considered stable enough to land in the next iteraction of Debian Jessie as their main init system.

What it is *experimental* is the integration of systemd with Ubuntu, or the use of the PPA instead of the main repositories, and even so, I have a functional systemd Ubuntu installation of Trusty with GDM/Gnome 3/Gnome Shell (upgraded from Raring), and haven´t found any partypooper problem *yet*.

Bugs caused by the itteraction of systemd with Ubuntu, like trying to install two DM´s at the same time and both infunctional, is off topic, as they should be addresed by developers. Asking about how to use systemd, replace the system init provider from upstart to systemd, etc. are on topic, as they can be addressed by users and aren´t actual problems that are best served by developers intervention.
I'd say that's similar to custom compiled kernels or mainline kernels, which are off-topic as far as I am aware. At least that would make sense from the support perspective.

As you said in one of the comments, there are other distributions available that have already integrated systemd and which would be more appropriate to study systemd.

I wouldn't say it's off-topic because it's Ubuntu+1, but a core software component that's not completely integrated and ready for and Ubuntu release. Users wanting to try out systemd, like users who want to try out Ubuntu+1, should get involved in bug reporting instead of posting here.

Correct me if I'm wrong.
