/home/albi/.config

Install

Bootloader-specific settings

Some of the below options might be useful if you have an older setup.

• BIOS instead of UEFI:

  # Use grub instead of systemd-boot:
  # Disabling systemd-boot enables GRUB
  boot.loader.systemd-boot.enable = false;
  boot.loader.grub.useOSProber = true; # if dual booting
  boot.loader.grub.device = "/dev/sda"; # if needed

• Garbage PC™ (Intel Atom Bay Trail Whatever): Nix Wiki, Arch Wiki

  boot.loader.efi.canTouchEfiVariables = false;

Scripts

Some reproducible interpreted scripts you might find useful while working with Linux. If you have Nix installed (you can run nix-shell), all of them are runnable using the below commands, without having to explicitly install dependencies, like Python or Python packages. The individual scripts contain more information on the specifications used and how they are implemented.

• ./scripts/print-env.py
  • Pretty-prints the current environment variables. Sorts, colors and splits array variables onto new lines.
• ./scripts/list-desktop-files.py
  • Lists .desktop files. These are used to populate app launchers and when opening URLs.
• ./scripts/list-mimeapps-lists.py
  • Lists mimeapps.list files. These are used to set which .desktop file is used when opening a URL.
• ./scripts/list-minecraft-saves.py
  • Lists Minecraft saves by searching for level.dat files. You will most likely have to update the code for your specific use case.
• ./scripts/list-non-empty-dirs-from-env-var.py XDG_DATA_DIRS
  • Given the name of an environment variable (XDG_DATA_DIRS in the example), lists all non-empty directories referenced by it.
• ./scripts/mkmedia.sh
  • Initializes a /media directory for Linux ISOs, using my preferred directory layout.
