We still have /etc/default/...
That's used more and more, as Debian/Ubuntu use this as main place and what I
meanwhile prefer. Put the distribution default in /usr/etc/default/..., source
that first, and afterwards source /etc/default/... if that exists. Also solves
the "adjust config during update" problem we face with %config files or
/etc/sysconfig.

I agree, especially as this not always works, depending on how the user did
login or even not, but the job is run by a systemd.timer, cron or something
similar.
