I'm wondering how best to generate the "X509v3 CRL Numbers" numbers, e.g. Strictly serial. Store and increment a counter. Use the time of generation (plus some nonce). This doesn't require a counter but does provide unique, monotonic values. Random values. These are unique but not monotonic. Relatedly, how often should one change the CRL number?
