NixOS Setup Guide - Configuration / Home-Manager / Flakes

!!!Resources, Timestamps, and Extra Notes Below!!!
--------------------
In this mini-course I try to demystify the whole process of setting up NixOS on your personal system.
This course covers:
NixOS (configuration.nix and hardware-configuration.nix)
Home Manager (home.nix)
Flakes (flake.nix)

This video is for entertainment purposes only.
Some aspects/topics might change in future updates.
Not everything is 100% correctly explained or information is left out. This is done to get the point across and keep everything accessible for newcomers.
--------------------
Notes ( that I forgot to mention and will probably be updated with more information):
Flakes are currently only supported on the unstable version of NixOS
Home-Manager can be updated again by just running:
$ nix-channel --update
Changing by-uuid in hardware-configuration.nix to *by-label*, does not mean you can always use this for other systems as mentioned at 0:55:00. Depending on your system, other kernel modules are needed for the system. In this case, it's highly recommended to still run:
nixos-generate-config --root /mnt
But this is useful if you want to reinstall the profile on the same formatted system.
nix.settings.auto-optimise-store is currently only available on unstable
I know it's curly. But I like squirly :)
