Does the multi-user mode work on SELinux-enabled systems and, if not, is it possible to install in single-user mode? The default installer's multi-user mode doesn't work with SELinux enforcing (https://github.com/NixOS/nix/issues/2374), and I didn't see a flag for enabling single-user mode when I used `install --help`. (There are some projects to make SELinux support work like https://github.com/dnkmmr69420/nix-with-selinux, but it's not clear to me if that would even work with this installer in particular.)
