Automated initial OS setup

This weekend I finally got done something I probably should have back since I got my first computer nearly two decades ago: a script to automate the initial setup of a new OS installation. After all, I've been using Linux for most of that time and it wasn't even that hard to do. I guess I never felt fully confident in my setup itself to bother replicating it.

The biggest hurdle was that I have also always wanted synchronization of my most valuable files across all my devices... Which I finally got done this time too in a simple enough way, just how I like it. Sure, it's always been possible, but nice tools like rclone bisync and tailscale make it significantly easier nowadays.

The script is here. It ended up being a handy opportunity to practice my Bash too, and it's working pretty well for a minimalist like me. Still, suggestions are welcome!
