I working on a project where I'd like to distribute several Fedora spec files with some local modifications (which would not make sense in Fedora).

Now, my organisation requires me to put all third-party code under third_party/ directory of the repo, along with readme file describing where it was taken from, list of local modifications and original LICENSE file.

Ok, so I go to https://fedoraproject.org/wiki/Licensing:Main?rd=Licensing#License_of_Fedora_SPEC_Files where I can find that all Fedora spec files licensed under MIT.
Since I'm not sure which MIT variant do you use, I go and read FPCA which says ""MIT License" means the license identified as "Modern Style withsublicense" at <https://fedoraproject.org/wiki/Licensing:MIT#Modern_Style_with_sublicense>."

So I go to https://fedoraproject.org/wiki/Licensing:MIT#Modern_Style_with_sublicense to find there things like "Copyright (c) 1998, 1999, 2000 Thai Open Source Software Center Ltd" and "The above copyright notice and this permission notice shall be includedin all copies or substantial portions of the Software."

And I'm not sure if Thai Open Source Software Center actually has copyrights for Fedora spec files.

So, which MIT license text should I use?
