Right, we don't want to stand in the way of people with more powerful hardware and more bandwidth. This is a concern I brought up the last time we had this discussion. [0] The limitations of our current hardware should probably not be baked into the Guix codebase. On the other hand, I think that for each user that comes to IRC or help-guix to ask about this, there are several more that give up or (hopefully without too much frustration) figure it out. It's a bad user experience. [0] http://lists.gnu.org/archive/html/guix-devel/2016-04/msg00386.html > Is there a way that we can mark that it hasn't been built yet on > hydra?

I think that the current error message is clear that the solution is to try again with --fallback. I think that if people won't read this error message, they probably won't read a longer error message. Although perhaps the list format will catch their eye.
