Are you proposing to implement a RFC4122 compliant UUID? Which UUID version? Which dependencies would it require? I guess something RFC4122 compliant based on openssl for example would work. Adding chunks of fragile code nobody is gonna maintain or adding additional dependencies like libuuid - probably not. I suggest we wait for Willy's feedback, but I want to stress that this may not be as simple as 5 lines of standalone C code ... we certainly don't want to act like we are generating standard compliant RFC4122 UUIDs when that is not really the case.
