Thanks for this report! I would have expected that to work, and it's 
tricky to test without hardware.

Before getting into the weeds, I agree with you that it shouldn't block 
the update, especially if it was already broken. I'm not a Guix 
committer, but as far as I'm concerned this series is ready to merge.

As far as riscv64, it looks like 
chez-scheme-for-racket-bootstrap-bootfiles created "portable bytecode" 
bootfiles ("tpb64l") instead of native riscv64 ones. You can confirm if 
that is the problem (or at least *a* problem) by checking if the 
lib/chez-scheme-bootfiles directory in the bootstrap package's output 
contains a directory named "tpb64l" instead of "trv64le".

If that is indeed the problem, most likely either there is a bug in my 
change to rktboot's auto-detection or there were additional 
auto-detection bugs I didn't find.

One way things could have gone wrong is if Racket BC returned something 
unexpected from (system-library-subpath #f). It would help to confirm 
the results of that, (system-type 'os*), and (system-type 'arch).

In principle, if the problem is only with rktboot's auto-detection, it 
should work to just keep supplying the explicit --machine flag for now, 
i.e. drop patch 3/3 from this series.

Racket doesn't have CI on riscv64 or distribute builds for it, but 
Matthew Flatt did share a nice screenshot earlier this summer of 
DrRacket running on a STAR64 :)
