dotfiles

This repository uses nix and home-manager to manage dotfiles.

Installing

Clone this repository into ~/.config/nixpkgs (on Linux) or ~/.nixpkgs (on Darwin). Create a home.nix or darwin-configuration.nix file and import the correct module from machine

Encryption

Some proprietary firmware is required for linux to work properly on a t2 macbook. Broadcom licensing prohibits redistribution of the wifi and bluetooth firmware. I've encrypted the firmware package to avoid any legal issues from storing firmware ripped from my macbook in a publicly accessible git repo. These files are encrypted with git-crypt. To decrypt, run gpg --decrypt local.key.asc | git-crypt unlock -.

Known Issues

Sometimes on macos in zsh, darwin-rebuild will fail with an error due to the NIX_PATH. This is most likely because nix-darwin sets up the NIX_PATH in /etc/zshenv, but the nix-daemon script overwrites this in /etc/zshrc, which is loaded later. To fix, replace the line in /etc/zshrc that loads the daemon with:

# this will overwrite the existing NIX_PATH set by nix-darwin in /etc/zshenv
if [ -e '/nix/var/nix/profiles/default/etc/profile.d/nix-daemon.sh' ]; then
  OLD_NIX_PATH="$NIX_PATH"
  . '/nix/var/nix/profiles/default/etc/profile.d/nix-daemon.sh'
  if [ -n "$OLD_NIX_PATH" ]; then
      NIX_PATH="$OLD_NIX_PATH"
  fi
fi

This should be safe since /etc/zshrc is not managed by nix and is only modified once on install. Alternatively, set programs.zsh.shellInit to export OLD_NIX_PATH="$NIX_PATH", and programs.zsh.interactiveShellInit to:

if [ -n "$OLD_NIX_PATH" ]; then
  NIX_PATH="$OLD_NIX_PATH"
  unset OLD_NIX_PATH
  echo Reset NIX_PATH
fi

This will work because zsh.shellInit is run in /etc/zshenv after nix-darwin sets up NIX_PATH, and zsh.interactiveShellInit is run in /etc/static/zshrc, which is executed after the daemon script resets NIX_PATH.
