Changes

* Units written by generators are removed when the configuration is  reloaded. That means the lifetime of the generated units is closely bound to the reload cycles of '''systemd''' itself.

* Generators should only be used to generate unit files and symlinks to them, not any other kind of configuration. Due to the lifecycle logic mentioned above, generators are not a good fit to generate dynamic configuration for other services. If you need to generate dynamic configuration for other services, do so in normal services you order before the service in question.

systemctl daemon-reload has be run after each modification of a unit. Hence generated files by generators will be erase and generators rerun. <ref>https://www.freedesktop.org/software/systemd/man/systemctl.html#daemon-reload</ref>
