Thank you for explanation, I installed these packages system wide and
got symbolic links. I prepared the patch for gnu/system.scm but I
unsure about the way I used to check packages availability
(find-packages-by-name). I see only the problem when one user
installed the package and other don't — the new shell will be added to
the list anyway. But I not found how to check that package was
installed system wide.

And generally should we check that shells really installed or just
unconditionally add paths to /etc/shells? I will modify patch then.
