Jigsaw/JDK requirements

[Jonathan Gibbons]

So you do end up with "double inodes" when you rename a file ...

I agree the user illusion is good, but I still say it is heavyweight 
under the covers.
For occasional file renames, I don't think it's a big deal; it is 
arguably more of a big
deal if we were to rename most of the files in the JDK repository.
