Hi Rutherther,

I did some more tests and found out that the `guix` package compiles successfully if I make my /tmp directory use my root BTRFS partition instead of Tmpfs. Somebody on Github[1] thinks this has to do with the 16kb Tmpfs sector sizes that Asahi Linux uses due to having a 16k page size instead of 4k that x86 machines use and also filed a report on debbugs[2]. I'm not sure why Guix worked previously, but I also noticed while testing that I couldn't compile an old (August) version of the Guix repo either so I'm guessing that an Asahi Fedora update changed the /tmp configuration and that's when the issue started.
