Hi! A quick follow up on that, as I have had some discussions with a few of you, and also my IT department.
*Context*: at the University of Reading, we have that facility that allows the deployment of vms on-demand to the campus. I work primarily on reproducibility in science, and managed to convince our IT dept to provide guix as default to all users. *Hiccups*: we provide home dirs as nfs drives through the network. Using guix, we are thinking of creating one nfs drive, shared by all users, to contain /var/guix and /gnu/store, symlinked from /. As I understand, that should work, until a user decides to run "guix gc" (which would clear wrongly assumed unused profiles) or maybe until a user decides to launch several vms (which is theoretically possible, but doesn't happen often). Efraim suggested using a shared daemon ssh-ing GUIX_DAEMON_SOCKET. We would probably run this on a separate vm. We are however unsure how it would behave when /var/guix/daemon-socket/socket is itself on an nfs. In theory, it should work, right? Are we missing something? Thanks a ton!
