Getting Nix onto legacy distributions can be difficult and the official installer is not always a viable option, especially when considering reproducibility and automation.

This approach is different from others in that we:

• Package using distribution-native packaging formats (deb/rpm). And use these packages to manage systemd and environment integrations.

• Create a /nix/store imperatively as a postinstall hook. This uses a prepopulated Nix store embedded inside the distribution-native packaging format.

• Properly cleans up after uninstallation. We use package manager hooks to cleanly remove any traces of Nix post removal.

To achieve a reproducible setup for these distributions that doesn't rely on pulling files from the internet at install-time.

These installer packages are intended to be used in a one-shot fashion to bootstrap the Nix installation, and then let Nix deal with managing itself from that point on.

We provide prebuilt installers at https://nix-community.github.io/nix-installers/
