Just because I know something about it... NT only complies with the most basic levels of Posix as it doesn't fit the perogative of MS to include futher levels of Posix standards. Posix, as you said is only a set of 'policies and procedures' which are recommended for OS to comply with... the purpose being portability and compatibility. IIRC the SysV bootstrapping procedure, and the associated mess of run levels and rc files, doesn't appear in Posix but I very well could be wrong. The fact that there are a number of levels of Posix compliance possible speaks to the intent of the designers of the Posix system. --Steve To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
