Looks fine as far as it goes, but we should note somewhere that FreeBSD's MD5 algorithm is expected to be better protected against this by virtue of the fact that it does something like 1000 iterations of md5. The algorithm would probably need to be comprehensively broken to affect the security of FreeBSD password hashes.
