Many thanks, you're right.
It seems to be a bug in GNU fileutils-4.0

There is no NFS file system involved.

I've made a simple test in a fresh directory

mkdir TT
touch a
ln a b
mv a b TT

and I get the same error message that
TT/b is missing.

Having loaded zsh/files
it works just fine.

So, I'll have to write a bug report to gnu.

Thanks for solving this mystery,
Helmut.
