Hi Guix, I really like the fact that Guix can substitute derivations. It’s a great way to transfer a profile from one powerful machine to a weak machine without having to set up SSH for “guix copy” first.
I just build a profile on machine A, and then on the weak machine B I do guix build --substitute-urls="http://A:8000"; /gnu/store/…-profile.drv and all items for that profile are copied to B. Did I say *all items*? Well, … grafts are not included, because graft derivations are marked as not substitutable. Can we change that conditionally? I would really like to avoid having to build grafts on B when they have already been built on A. -- Ricardo PS: please keep me in Cc as I’m not subscribed to guix-devel at the moment.
