I am not a systemd developer, so I may be talking BS here, but in this case it
seems to me that the *.conf file should be processed line-by-line, i.e., the
order matters, so if you are setting the mode to 0755 and then to 0777, the
last one "wins".  Of course, there may be cases when the lines are really
conflicting, in the sense that they do things incoherently, but that is a user
error, not exactly a systemd concern.

Cool.

That sounds like a good plan to me.  Thank you for adjusting the title to
reflect this.
