You can set the GUIX_DISTRO_AGE_WARNING environment variable to a string
like "9d" for 9 days. The suffix can also be "w" or "m" for weeks or
months.

Re: Checking for substitutes
Hi Ricardo, I tried it. It provides interesting statistics, but always considers all packages in Guix rather than just the ones I care about. You can pass a manifest to “guix weather”. Found it in the manual - great! And a quick look at the source shows that it shouldn't be too hard to make it print a list of the packages that are not available as substitutes. It's on my to-do list... Thanks, Konrad.
Guix "days old" variable
Hello. I check updates:
guix refresh emacs
gnu/packages/emacs.scm:116:13: emacs would be upgraded from 25.3 to 26.1
and would like to install only this one update:
guix package -u emacs
guix package: warning: Your Guix installation is 16 days old
...
Can I change threshold for this ("NN days old")? What is this variable?
Thanks.

You use it like this: guix weather --substitute-urls="…" -m my-manifest.scm and it tells you what the current substitute coverage for your manifest is for all substitute servers you interrogated. (It does not give you a total percentage when all servers are considered, unfortunately.) -- Ricardo

Re: Checking for substitutes
Hi Tim, Thanks for your explanations! I will try out the script you posted last year. From your description it sounds like good enough to solve my routine problem, which is that compiling Qt runs out of memory on my machine unless it's close to idle. No way to have Emacs + Firefox + Qt compilation with 8 GB of RAM :-( > There’s also the ‘guix weather’ command. It is supposed to provide info > about available substitutes. I have not made much of use of it, though. I tried it. It provides interesting statistics, but always considers all packages in Guix rather than just the ones I care about. Konrad.

There’s an old feature request for this: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=26608 I looked into it some time ago, and there were a lot of blockers. See https://lists.gnu.org/archive/html/guix-devel/2017-06/msg00190.html for details. At the end of that thread, I posted a small shell script that scrapes the most recent fully evaluated commit from the build farm. That way, you can update to that commit, and have a much better chance of getting all substitutes. To be honest, I only use the script if I see something like Icecat building. In that case, I rollback to the latest complete evaluation. There’s also the ‘guix weather’ command. It is supposed to provide info about available substitutes. I have not made much of use of it, though. Hope that helps. -- Tim
Checking for substitutes
Hi Guix, I wonder if there is any way to check if substitutes are available for a given set of packages (e.g. a single package with its dependencies, or a complete manifest). The context is optimizing package updates: if I know everything I need is available as a substitute, I can do an update immediately, but if big packages need to be built locally, I prefer to wait until my computer is idle. Ideally, I'd like "guix package" to have an option –only-substitutes that will stop if local builds are required, providing a list of the packages that must be built. Konrad.
