This is a design feature of case-insensitive file systems.  It is not
coreutils' fault that the underlying OS refuses to do case-insensitive
renames when the file system cannot tell the two spellings apart, rather,
mv is merely reporting the results of its attempt to use the rename(2)
syscall.

On case-insensitive file systems, a case-changing rename requires a
two-pass rename:
mv webboy webboy1; mv webboy1 WebBoy
