The failure is:

--8<---------------cut here---------------start------------->8---
21228 mount("none", "/tmp/guix-directory.5sVcGc//dev/pts", "devpts", MS_NOS=
UID|MS_NOEXEC, "newinstance,ptmxmode=3D0666,mode=3D6"...) =3D -1 EPERM (Ope=
ration not permitted)
21228 exit_group(1)                     =3D ?
--8<---------------cut here---------------end--------------->8---

The problem may be that the kernel does not support
CONFIG_DEVPTS_MULTIPLE_INSTANCES.  Could you check that in
/proc/config.gz or similar?

The other problem is that there=E2=80=99s no error reporting, which doubles=
 user
frustration.  David, could you look into it?  :-)
