Some active services have Wants dependencies on those, I think. If you
want a good overview over your systemd, rather look at 'systemctl
--failed' and 'systemctl list-unit-files'.

No idea why it shows that, but arch-modules-load.service is part of
initscripts.

Reboot and Shutdown only work in KDE when you use kdm, not with xinit.
There's some special care to be taken when using xinit/startx with
logind - explained here:

Same logind issue as above.

If you install systemd-sysvcompat (now the default), you can keep using
KDM's default poweroff and reboot commands.

Interesting, but I don't know. This may be a polkit setting. If you find
out, I'd be interested.
