I learned it very on in my career, and what is "obvious" to one person can be "obscure lore" to another. It's probably too much tutorial information for the su man page, but some kind of "system administrators tutorial/guide/handbook" might be a great place for this kind of "so you want to create system administration scripts as root --- what are best practices for security/robustness/etc.". For Debian systems, maybe contributing something to The Debian Administrator's Handbook, at https://debian-handbook.info? I'm not sure what's the best place for Fedora/RedHat/Ubuntu system administrators. - Ted
