Hi,

Did you define an environment along the lines of the example at
<https://guix.gnu.org/manual/devel/en/html_node/Inferiors.html>?

If so, this should behave in exactly the same way as a =E2=80=9Cregular=E2=
=80=9D =E2=80=98guix
environment=E2=80=99, so I=E2=80=99m not sure where the issues regarding ac=
cess to the
tty come from?

Depending on the use case, another option is to not use inferiors at all
and simply do:

  guix pull --commit=3DXYZ -p ./my-old-guix
  ./my-old-guix/bin/guix environment --ad-hoc whatevern

But maybe I=E2=80=99m missing something, let me know.  :-)

Thanks,
Ludo=E2=80=99.
