My NixOS configuration.

NixOS

This repository contains my NixOS configuration files.

As I use the same configuration across multiple machines, the focus is to create a configuration that shares as much between machines as possible. This is found in the shared directory. The hosts directory contains multiple machines and the specific additions and modifications to the shared configuration.

An additional focus is to allow the repository to be up-to-date on all my machines while not containing local untracked/uncommited changes for the configuration to work, as this would be a hassle to keep track of. Instead, the configuration for a given machine is symlinked into the root of the directory, after which a normal sudo nixos-rebuild switch or sudo nixos-rebuild boot will build the desired configuration.

Considerations

Personally, I am not a big fan of some of the file splitting this configuration leads to, as some of the host specific configuration files are only a couple of lines long and modify a single option. However, I do think that this structure allows for additions to be easy and rather simply, if further machines are added to the host list.
