First, guix-daemon is running as root, right?

That seems to suggest that there=E2=80=99s a lock on each of these.  What d=
oes
=E2=80=98ls -l /nix/var/nix/userpool/=E2=80=99 report?

Can you also try running guix-daemon in strace, and then check then
fcntl(fd, F_SETLKW, _) calls for user locks?

TIA,
Ludo=E2=80=99.
