I have built my own custom repo for a custom Manjaro build but I am not sure how to sign them properly. As mentioned here How to become a contributor to manjaro repositories? I can do this step by step it seems, but then I wonder even if I achieve this, what happens if say I reinstall my personal Linux distro, is the signing still going to work?
What is the best procedure to sign custom repos? And also, how necessary is it? Thanks!
