They do. Without dependencies on external I/O, the startup procedure should be deterministic. FreeBSD assigns PIDs sequentially, and if those services are started in the same order, the daemons will always get the same PIDs. (Some operating systems, e.g. OpenBSD, will assign PIDs in random distribution.) Amazing, how the belief in magic and the loss of the assumption of determinism has infiltrated popular computing. -- Christian "naddy" Weisgerber naddy@mips.inka.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
