Per setpriority(2), the only was this can happen is if we’re trying to
set a nice value lower than the current one:

   EACCES The  caller attempted to set a lower nice value (i.e., a higher process priority), but did not have
          the required privilege (on Linux: did not have the CAP_SYS_NICE capability).

Could it be that you’re running the daemon with “nice guix-daemon …” or
something like that?

Thanks,
Ludo’.
