QCOW2 images get GC’d rather quickly, because they take up a lot of space; see in particular: https://git.savannah.gnu.org/cgit/guix/maintenance.git/commit/?id=4a720a03f9d190f7b1abc883f49d51a95a5f58a9 https://git.savannah.gnu.org/cgit/guix/maintenance.git/commit/?id=0bf8202de811364ebd79e390fcd039f7936b6ea7 I guess it’s OK for Guix System ISO images because a fresh one gets built at each evaluation, roughly, but perhaps the Hurd images are not rebuilt frequently enough and the changes that they’re GC’d are higher. I don’t have a good solution for that, we’re consuming storage space too quickly with all these images currently. :-/ Thanks, Ludo’.
