-# Previously, our systemd unit files were installed below "/etc/systemd/user/"
-# and activated semi-manually by calling
-# `systemctl enable /full/path/to/systemd-unit.service`. This was the only way
-# to make short names like "subapp.service" usable, which is a major
-# convenience win in everyday operations. On the other hand, it also makes the
-# SubApp start on bootup, which isn't always the desired and safe behaviour.
-#
-# To improve upon this situation, we're now moving the systemd units to
-# "/usr/local/lib/systemd/system/", which, according to systemd's manual, is
-# the more suitable location and also enables the use of short service names
-# even if a service is not enabled and thus doesn't automatically startup on
-# (re)boot.
