I do find it funny the idea of taking an office PC that was likely just being used for spreadsheets and emails and making it run databases or route packets across network segments
@laru the really interesting thing is that some init systems like openrc actually do the opposite where defaults are in /etc/init.d, but customizations to those scripts are in a separate /etc/conf.d, which kinda makes more sense
(and then systemd has the whole thing with package defaults in /usr/lib/systemd and custom stuff in /etc/systemd instead)
@wolf480pl In a way I can see it as being the "default" values that result in what's in the real config file (/boot/grub/grub.cfg or similar) but often times it's /etc/default/grub that's configured by the admin and grub.cfg itself is often advised to not mess with.
