Please excuse my hijacking this thread: I have been trying out=20 configurations to get Guix working on the cluster I have access=20 to, without root access for the daemon, and one problem I ran into=20 is a curious bug when the store is on an NFS share. See=20 https://lists.gnu.org/archive/html/guix-science/2021-03/msg00010.html=20 (Case 3). In your setup, is the store on an NFS share? If so, did you do=20 anything special to get that working?
