How to make a separate user setting of something in GNU/Linux?

Question

linux

The question came up when I wanted to set up a folder for saving pdf, which produces a virtual printer pdf-cups. It turned out that the settings are here:
sudo nano /etc/cups/cups-pdf.conf
I'm sure that such a personal user setting could be done somewhere in ~/ or in ~/.config/, that is, without administrator rights.
With awesome, you can do something like this to create a custom config:

mkdir ~/.config/awesome
cp /etc/xdg/awesome/rc.lua ~/.config/awesome/rc.lua

Now the question is:
Is there any standard for these user config files? In what order are they processed, from which directory are they taken, etc.

Answer 1

root? :D

Answer 2

Google it, maybe pdf-cups can be fed the config name as a parameter. Or make a symlink /etc/cups/cups-pdf.conf to the user config
