Please see:

https://www.freedesktop.org/software/systemd/man/systemd.generator.html

i.e. generators are invoked whenever a reload cycle begins, and output
their units into a specific directories that are flushed our when the
reload cycle ends. i.e. everytime "systemctl daemon-reload" is invoked
the files generated on the current cycles are removed, and the
generators started again to generate a new set of files. Whateever
they generate has very clear, very volatile semantics: issue
"systemctl daemon-reload" and its all gone.
