Symlinks in a subdirectory that is to become target rootfs are sometimes dangling because they link to canonical file names that are not present on the host, but are present relative to the target rootfs root. Don't copy over dangling symlinks when noclobber is enabled The -e test treats dangling symlinks as non-existent files. Add -h test that returns true for all symlinks. Cc: Yann E.
