Bugs

exFAT is a case-insensitive file system. Some things can behave unexpectedly, e.g. directory renaming that changes only case of some characters:

$ mv FOO Foo
mv: cannot move ’FOO’ to a subdirectory of itself, ’Foo/FOO’

This happens because mv finds that destination exists (for case-insensitive file systems FOO and Foo are the same thing) and adds source basename to the destination. The file system gets rename("FOO", "Foo/FOO") syscall and returns an error.
