That depends on what you call a bug.

The current behavior of the Guix package for Jupyter is not in conflict
with any written documentation for Jupyter, but does not respect a
convention that standard installations (via pip, for example) do
respect. This convention says that the default Python kernel for Jupyter
uses the same Python installation as Jupyter itself.

I'd vote for respecting this convention, and I'd be happy to work on an
implementation, but don't count on me for this before August.

Konrad.
