I don’t think you’re doing anything wrong.  Could anyone of you who
experience this problem strace guix-daemon?  I’ve thought about this and
don’t understand where that EACCES (“Permission denied”) comes from.

Specifically, you’d have to run something along these lines as root:

  strace -f -p $(pidof guix-daemon) -o log

and then, as root or non-root (it doesn’t matter), run, say:

  guix build curl -S --no-substitutes

Thanks in advance!
