To rephrase, I found it extremely hard to get that particular Guile derivation to build successfully, it failed to build 12 times, and only succeeded when I added new hardware to attempt on (I'm guessing the particular issue I was encountering was exacerbated by more cores). Unfortunately, I also think that you finding it easy to build actually contributes to the problem here, since it makes finding and addressing issues like this harder. >> Space is running out on bayfront, the machine that runs the coordinator, >> stores all the nars and build logs, and serves the substitutes.

Since this email got a bit delayed when I sent it, things have moved on a bit now. 90% disk usage was the threshold I had in mind for bayfront, and that's now pretty much been reached so I've paused all the agents. My plans for how to address this have also developed a bit as well, but it's still going to take a month at least to get things going again.
