The locations mentioned in the man-page are definitely correct for
Fedora and RHEL,  the only systems using systemd at the time I wrote
the systemd parts of the man-page (in 2013). For these distros they are
still correct.
Now Ubuntu may have changed some of the paths when it introduced
systemd. It may also be the case that Ubuntu does use an old version of
systemd that does not yet support the user specific units (in
/etc/systemd/user). Can somebody please confirm if other Ubuntu
versions (probably later versions) do use /etc/systemd/system?
If I can find some time I may try to clarify the man-page with the
alternate location if we can get more clarity on this.
