Hi Pjotr,

Thank you for sharing your plans.

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
 -- pack -f 
 -- system *-image

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, 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. :-)
