Notable files for reading

If looking for help and examples how to do things in Nix, or having any questions or suggestions, please file an issue and I can try to help when having some time. This setup has been my learning process for the Nix language and ecosystem, and is still changing when I find out how to do things better.

There are a few things here that I would’ve found interesting and helpful when jumping in to Nix:

• A reproducible desktop/emacs/config.org with Wayland and native compilation support, elisp packages from Nix.
• A reproducible core/nvim using Nix as the source for libraries.
• Firefox configuration which takes addons from Nix and sets as many settings as possible from Nix.
• Wayland screen sharing and streaming using OBS Studio and a video4linux loopback device to work with Zoom being a garbage piece of software.
• Tiling Wayland compositor Sway setup.
• Setup for perfect Linux sound and all the Bluetooth codecs using Pipewire and Bluez.
• Reproducible Cups setup to have our home printer always working without touching the Cups admin.

New system installation

• Use the unstable build of NixOS 21.05.
• Boot into the installer.
• git clone https://github.com/pimeys/nixos /tmp/nixos
• cd /tmp/nixos && git submodule update
• DISK=/dev/disk/by-id/... ./partition.sh
• mv /tmp/nixos /mnt/etc/nixos
• nixos-generate-config --root /mnt --show-hardware-config
• Add output of the previous file to a new config in hosts
• Add the new host to flake.nix
• nix-shell -p git nixFlakes
• Merge the hardware config with the dotfiles in /mnt/etc/nixos
• Install NixOS: nixos-install --root /mnt --flake /mnt/etc/nixos#XYZ, where
• `XYZ` is [the host you want to install](hosts/).
• Reboot!
• Change your root and $USER passwords!
• chmod -R pimeys:users /etc/nixos
• ln -s /etc/nixos /home/pimeys/.config/nixpkgs
