Installing guix on nixos system

[Roy Lemmon]

Hi,

I am trying to install guix on my nixos system. I am using the shell script
provided on the guix installation page:

https://git.savannah.gnu.org/cgit/guix.git/plain/etc/guix-install.sh

All works well until the script tries to install the guix-daemon service.
It cannot install it in /etc/systemd/system and so the daemon cannot be
started. See below.

Has anyone come across this problem ? I thought /etc filesystem was
writeable as that is where configuration.nix lives.

Thanks
Roy.
