OK, but Fedora users will always have Fedora TeX distro due to
dependencies. If they are not able to follow installation instructions
for TL, they should not use it or ask someone else to install it for
them. Now tlmgr from Fedora does the right thing, it says that the
user is trying to update Fedora TeX distro by non-Fedora tools which
will not work.
