I personally find much  interesting the last discussion, as a general rpm
improvement of course. Maybe at a certain historical moment the battle  tar
vs star was  due to selinux problems (xtattr and the like). It is obviously
a hypothesis. But maybe these problems that  were present are not such any
more or, almost, with minor problem (*

)

Ma perhaps this are patch not upstream: to do verified.

But the discussion could deviate again..................*
