Hello Maxim, >> 1. rustc bootstrap from 1.39 (the itch to make it faster comes back >> everytime I have to build it ;-)). > > I'm nearing completion on this front.

Great! As we are going for a full rebuild, maybe we should also consider some of the Thiago fixes targeting core-updates-frozen such as https://issues.guix.gnu.org/50239. > Sadly the plain .tar file was/is not covered by tests (and not easily > so), but if his was my only omission, it should be correct (TM). > Attentive review needed :-). This seems reasonable and I'm currently rebuilding the world to test this fix and the Python fix. I should maybe apply your Rust bootstrap patch if you have it around to gain some time. Thanks for all those fixes! Mathieu
