No, it doesn't because you can have many versions installed in
parallel and can choose by setting PATH. I have 17 working versions in
addition to the Fedora packages. However, TL after installation says
that its binary should be at the begining of PATH which is not done by
the installation procedure, a user must do it. What TL dos is
examination of existence of a previous version and optional copy of
the settings.
