I have configured guix such that the $localstatedir is /gnu/var, so I
only have to export /gnu.

Correct. With a shared store there must be a shared daemon. An
alternative setup would be to have completely separate stores and reduce
build work by using ‘guix publish’.
Unfortunately, I have not yet been able to test a setup where the local
‘guix’ command talks via SSH/socat to a central guix-daemon. (I’ve been
trying to improve the performance in our situation where the store is
located on a central file server and the daemon operates on the NFS
share. This is rather slow here and could only partially be improved by
