Its already answered how to fix it after installation, Thats not the 
only issue, The real issue is guix isnt doing this by default after 
installing it, You dont expect users to make crazy steps after 
installation just to make guix works properly.

Solution to this must developed in a way that when user install guix 
package then he type guix install x then it should work without further 
configs.

Otherwise we have snap and flatpak which both are better than guix not 
just with lower complexity but even more security. (snap use 
lxc(container)+apparmor(mac), flatpak use bubblerap (namespace/seccomp), 
while guix doesnt use anything by default).
