Regarding NixOS system configurations, the major benefit of flakes is that they bundle nixpkgs (and possibly further dependencies) along with the configuration files. The nixpkgs version and the configuration files Read more…
In an earlier post, I talked about how you can build an out-of-tree Linux kernel module in a Nix derivation, i.e., package it in Nix. However, for quick prototyping, sometimes you want to just enter $ make in your shell, for example to check if everything compiles. Out-of-tree module projects Read more…
… Now I can’t log in and my system is broken. This is what essentially happened to me recently 😄. Luckily, I was able to fix my system. But let’s go through what happened step by step. Disclaimer: This guide is not meant for absolute Linux beginners. To follow the Read more…
