That's really helpful! How robust is your system to bandwidth > fluctuations and network hiccups? Network reliability has never been an issue for us when it comes to Guix. We serve /gnu redundantly with pacemaker so that we can take down one of the two Guix servers (they are VMs) without affecting availibility of programs and files on /gnu. > How big is your store, /gnu, /var/guix? We have about 2TB for /gnu. We never run =E2=80=9Cguix gc=E2=80=9D because= the Guix servers have no access to all the users=E2=80=99 shares, so it would be ove= rly aggressive in determining garbage. > How many users do you have?
