We’re slowly adding more variables for system.conf, which is explictly designed
to be extended with configuration snippets. The logical conclusion of this is
that every option in system.conf has a variable in the recipe to set it.
A more scalable approach would be to just use configuration snippets, ie you
write your watchdog assignments to /etc/systemd/system.conf.d/watchdog.conf.
This doesn’t involve touching the systemd recipe and will override the defaults.
What do you think about this approach?
