I'm following the RFC: "Locally assigned Global IDs MUST be generated with a pseudo-random algorithm consistent with [RFC 4086]. Section 3.2.2 describes a suggested algorithm."
I happen to be of the opinion that /dev/urandom is more likely to comply with RFC 4086 than the suggested algorithm, but I may have an unfairly low opinion of the distribution of timestamps and MAC addresses.
