Nixos Impermanence Desktop aka "Disko Inferno"

Configuration files for NixOS with an ephemeral root, erased every boot.

What this repo gives you:

• A flake-ified config
• Declarative Disk setup & management with Disko
• Ephemeral root (with either BTRFS or tmpfs) using the nixos impermamence module
• Modularized config files, including:
  • myparams.nix - initial set of install parameters (username, hostname, ssh-key & Desktop). Edit directly or via the install script.
  • packages.nix - packages divided into categories for easy modification / maintenence
  • users.nix - for extensive user configuation
  • desktop.nix - Allows multiple DEs (currently KDE or Pantheon). DE set with myDesktop variable in configuation.nix
• Install script:
  • nix-setup.sh - run this to install (full install instructions below)
• Helper scripts to manage after install (placed in /persist/scripts and added to $PATH)
  • changepass.sh - script to change user password in a running system
  • push-to-git.sh - script to push /etc/nixos files to a git repo
  • cruft.sh - shows all files written to / since boot (erased next boot)
