Nix on Guix?

[Benjamin Slade]

Hello Guix,

I'm trying to get the Nix package manager running on Guix. I followed the 
instructions at: 
<https://guix.gnu.org/manual/en/html_node/Miscellaneous-Services.html> and 
successfully installed it, but trying to install and/or run any Nix 
applications gives me permission errors.

I installed for the 'guix-system'; should I have installed for 'guix-user'? Or 
do I need to add my user to some Nix-related group? Or have I done something 
else wrong?

best,
 —Ben
