Quoth the manual (info "(guix) Setting Up the Daemon"):

      On some systems =E2=80=98/dev/shm=E2=80=99, which supports shared mem=
ory, is a
  symlink to another directory such as =E2=80=98/run/shm=E2=80=99, that is =
_not_ is the
  chroot.  When that is the case, shared memory support is unavailable
  in the chroot environment.  The workaround is to make sure that
  =E2=80=98/dev/shm=E2=80=99 is directly a =E2=80=98tmpfs=E2=80=99 mount po=
int.

I think that=E2=80=99s an occurrence of this case, no?  :-)

Ludo=E2=80=99.
