replacing a Nix installation
The Flox installer will perform some opinionated configuration of Nix, but Nix will still be usable. If you want full control of your Nix installation, see the instructions for installing Flox in the "Nix - Generic" tab above.
When installing over a previous installation of Nix the Flox installation will:
- Back out customizations made to the following files when Nix was
installed:
/etc/bashrc/etc/bash.bashrc/etc/profile.d/nix.sh/etc/zshrc/etc/zsh/zshrc
- Overwrite the system-wide
/etc/nix/nix.conf - (If applicable) convert the Nix installation to a multi-user install
- Reconfigure the
nix-daemoninvocation
These changes are designed to improve the overall user experience and make the Nix installation more reliable and easier to support, but it's worth noting that anyone wishing to revert to a "vanilla" Nix installation after installing Flox will need to re-install Nix.
If you are installing over a previous installation of Nix we suggest that you install Flox to a test machine or VM to gain familiarity with it first.
The version of Nix installed by Flox tracks the stable version of Nix in nixpkgs, occasionally adding additional backports or patches. Nix is usually updated monthly, although if Nix makes breaking changes, updates may be less frequent.
