Sometimes, `bindPath` will detect the source is a symlink and we are not using the new mount API which support symlinks (kernel ≥ 5.12 IIRC?). In those instances, we copy the inode to the target. But some callers may want to follow the symlink in such circumstances, we add a new default argument to the previous value and let caller decide for themselves.
