If the daemon wasn't configured to drop privs, it won't use nobody, anyway. And if the default config is to use nobody and you don't have a nobody user, you will get a warning or fatal error reminding you not to use the default setup. -- Archaic Under democracy one party always devotes its chief energies to trying to prove that the other party is unfit to rule--and both commonly succeed, and are right...
