OTOH, maybe it's worth rethinking the premises. if some region has low bandwidth if would still be better if one could fetch 90% of the substitutes from nearby. Thus some daily or twice-a-day rsync would help. It would also help if some day GuixSD gets some kind of "stable" (and some "testing") branch and users might subscribe to this, which would not have so many changes a day. I'm now finishing this discussion, as it is up to you (the core team) to decide. I just wanted to share the idea and arguments. --=20 Regards Hartmut Goebel | Hartmut Goebel | h.goebel@crazy-compilers.com | | www.crazy-compilers.com | compilers which you thought are impossible |
