From c37719764c7899608a36576ae1ba2b3cc3680e94 Mon Sep 17 00:00:00 2001 From: Adrian Kummerlaender Date: Wed, 18 Aug 2021 11:42:40 +0200 Subject: Flakeify home config Use nix flakes instead of niv for pinning dependency channels. First step towards merging my "nixos-system" and "nixos-home" configs into a single trivially reproducible flake setup.
