Yes, Chromium's build time is obscene. However, not providing substitutes for it duplicates that problem to the machines of every Guix user who uses ungoogled-chromium. In the time that it would take Guix's build farm to build u-c it could probably build many other packages, but users are in the exact same situation, so a substitute for u-c is likely more valuable to them than substitutes for those other packages. If it is possible to override the 6h timeout value for individual packages, I think that it would be worth doing so for u-c, and perhaps for Icecat and Linux-libre as well. > Right now we=E2=80=99re trying to improve build throughput in general but= your > proposal makes sense, of course. > > Thanks, > Ludo=E2=80=99.
