The system will automatically pull a cachix.nix at the root if one exists.
This is usually created automatically by a
sudo cachix use. If you're more
inclined to keep the root clean, you can drop any generated files in the
cachix directory into the
profiles/cachix directory without further
For example, to add your own cache, assuming the template lives in /etc/nixos,
by simply running
sudo cachix use yourcache. Then, optionally, move
These caches are only added to the system after a
nixos-rebuild switch, so it
is recommended to call
cachix use nrdxp before the initial deployment, as it
will save a lot of build time.
In the future, users will be able to skip this step once the ability to define the nix.conf within the flake is fully fleshed out upstream.
