I totally agree with the discussion. Is it a good idea to implement like
check made for zap_empty_root_password?
For zap_empty_root_password there is a conditional check if debug-tweaks
are enabled then zap_empty_root_password is
called. So can I use debug-tweaks to handle add_machine_name_loop_back in
the patch?
