Won't this fail if unlink is successful?

@shykes
func isNotExist(err error) bool {
switch pe := err.(type) {
case nil:
return false
case *PathError:
err = pe.Err
case *LinkError:
err = pe.Err
}
return err == syscall.ENOENT || err == ErrNotExist
}
So if err == nil, this will return false.
Great catch. This is my fault. Will update now.

@hamo please rebase
