Hello, I've been a long time Linux user but I had a 5 years break and I am coming back to it now.
I've been trying several Linux distributions in the past week, installing the packages and configuring them as I need with several different orders of success.
My last case was an Ubuntu installation that I was very happy with and pretty close to call it setup and done, until I installed virtualbox and restarted the system only to find it bricked.
Obviously I could try to drop into one of the terminals on ctrl + alt + Fx and fix it, but I wonder if I could be smarter about it and be more prepared for this kind of situation.
One of the starting points I think would be having a separate home partition from the rest of the system. I used to have it in the past and it was great.
But then what's next? What are the best FS I could pick for each type of partition? A performant one to keep the code and package manager cache, a journaling/snapshop based one for system, another type for game data, etc etc.
What if I would like to have a snapshot of working version of my system backed up somewhere ready to restore as simple as simple as possible?
How do you configure your systems in order to quickly recover from an unexpected bricking without growing some more white hairs, and squeezing as much performance vs feature for each of your use case?
This came pre installed and setup on my Garuda Linux install and it's great. By default it takes a snapshot before and after every update or installation through the package manager so if something goes wonky I can just select the previous snapshot in grub and be back up and running in seconds.
Also just recently installed bazzite on a laptop and it appears to automatically do something similar, but I haven't spent as much time with it to know the ins and outs yet.
