Updating nix

Sun, 17 Nov 2024 19:52:35 +0100

It seems like nix requires updating time to time. To update nix on a linux multi-user system:

$ su -
# nix-env --install --file '<nixpkgs>' --attr nix cacert -I nixpkgs=channel:nixpkgs-unstable
# systemctl daemon-reload
# systemctl restart nix-daemon

On a single-user system:

$ nix-env --install --file '<nixpkgs>' --attr nix cacert -I nixpkgs=channel:nixpkgs-unstable

Upgrading Nix

Using a package clone in home-manager

When proposing PRs on any opensourced software, you might want to use your fork instead of the currently nix packaged original source, especially when using nixos or home-manager.

# In modules/tlrc/default.nix
{ pkgs, ... }:
{
  nixpkgs.overlays = [ (self: super: { tlrc = super.callPackage ../../nix/tlrc.nix { }; }) ];
}

Add this module into your imported modules

# In modules/default.nix
...
  ./mmtc
...

Copy/clone the existing official module from nixpkgs in your tree, and prepare to patch the fetchFromGithub parameters, such as owner, rev and hashes.
