<para>For other platforms, including Mac OS X (Darwin), FreeBSD and

other Linux distributions, you can download a binary tarball. It

<para>If you plan to use Nix from a single non-root user account, it’s

probably convenient to change the ownership of the entire Nix store

doesn’t already exist. If you don’t have <command>sudo</command>, you
