Per setpriority(2), the only was this can happen is if we=E2=80=99re 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 p=
rocess priority), but did not have
          the required privilege (on Linux: did not have the CAP_SYS_NICE c=
apability).

Could it be that you=E2=80=99re running the daemon with =E2=80=9Cnice guix-=
daemon =E2=80=A6=E2=80=9D or
something like that?

Thanks,
Ludo=E2=80=99.
