Is it possible to make checkupdates “read” from a custom-made pacman.conf? I would like to make a conf file for the testing repo and pass it to checkupdates to see what updates are available in Testing.
I know of --config /path/to/file.conf for pacman. But I am not sure if i use pacman -Syu, would that “mess up” my local database.
I have looked at the code for /usr/bin/checkupdates but it is above my knowledge to make any changes there.
cat /usr/bin/checkupdates
!/usr/bin/bash
checkupdates: Safely print a list of pending updates.
