   I don't see "/usr/etc" in [0]. What I see is /usr/share/etc, i.e., 
   $(datarootdir)/etc. It's not clear why the latter name doesn't suffice 
   for this need, as files in $(datarootdir) are also supplied by the 
   distro and are read-only.

Or even sysconfdir ("read-only single-machine data") (where it is set
to /usr/share/etc or some other such thing).

This also seems very much specific to systemd based GNU/Linux systems
( https://www.gnu.org/gnu/why-gnu-linux.en.html ).
