I guess that the recent commit [1] by Efraim is part of this effort. :-) By container, what do you have in mind: guix time-machine --channels=file.scm \ -- environment --container or -- pack -f or -- system *-image ? 1: https://gitlab.inria.fr/guix-hpc/guix-past/-/commit/f9fe4d8ac2706834fcff477db8f5421de537d78e > Note that GeneNetwork requires a largisch MySQL/MariaDB (170GB) > which is also a snapshot in time.

I agree that Guix does not have (yet!) good management of large data set. The /gnu/store is not designed for that, if I have correctly understood. Even we have already discussed Content-Addressable Storage (CAS) on gwl-devel@gnu.org, AFAIR, we have not ended up with a good plan. Well, it will not be fixed on Friday. :-) But for sure, it is something to keep in mind. So, see you on Friday. :-) Cheers, simon
