Hi Guix, the CRAN updater downloads every upstream archive three times. The importer memoizes calls to the download procedure, but one download that is out of reach is the very first.
It is triggered by package-update/url-fetch in (guix upstream). It uses download-to-store, which will unconditionally fetch whatever URL it is given. I would very much like to parameterize download-to-store, so that we can optionally cache the results of its invocation. What do you think? -- Ricardo
