Change comment for SSH key

ssh-keygen -c -C "git@github.com:org/repo.git" -f ~/.ssh/my_ssh_key (Useful for "Comment for key 'ssh-rsa blahblah= (stdin)' does not match GitHub URL pattern. Not treating it as a GitHub deploy key.")

Add a forwarded display to .Xauthority:

Notes on rooting Samsung A Quantum on a Mac with Heimdall

Notes on rooting Samsung Galaxy A Quantum on a Mac with Heimdall

The A Quantum is actually the A71 5G from South Korea Telecom but it contains an S2Q000 Quantum random number generator made by IDQuantique.

This is a systemless install which means you don't bugger up the distribution. In a nutshell, Magisk patches boot.img and vmbeta.img which gives it a handy/dandy portal to rootworld.
