I am relatively new to Arch Linux and I really like its rolling-release concept. Now what I want to know is that before I do a system update via
pacman -Syu, I want to create a restore point so that should my system update fail, I can go back to the last good state my computer was in before the attempted system update.
This is because once when I did a
pacman -Syu on my Arch install, it b0rked my system and wouldn't boot. It happened when I still had minimal to no essential files on my computer so I did a fresh install. But now that I sort of slowly built a system much to my liking, I don't want to reinstall it from scratch and do all the things I have already done again should a system update break it. With a restore point, I can most likely restore my computer without the hassle of reinstalling everything.
So, how so I create, and use, restore points in Arch linux?
