Please excuse my hijacking this thread: I have been trying out 
configurations to get Guix working on the cluster I have access 
to, without root access for the daemon, and one problem I ran into 
is a curious bug when the store is on an NFS share. See 
https://lists.gnu.org/archive/html/guix-science/2021-03/msg00010.html 
(Case 3).

In your setup, is the store on an NFS share? If so, did you do 
anything special to get that working?

Best,
Sébastien
