Linux Toolkit and Handy Cheat Sheets

My memory is getting old I guess, so I need to jot down notes on various configurations to refer to from time to time. I manage my own database for all this code snippets, yaml files, init or configuration process. Below, I’ve shared some of my notes with you.

Handle pop-up notifications to users when a reboot is required (and ask for approval)

As an MSP, Acronis Cyber Protect Cloud can apply patch management to all devices of all your customers? that's great feature, but for now, the reboot isn't managed with the end-user consent. That's a bit annoying... 😶 Fortunately, we’ve got another ace up our
