But what if it's just an NFS client and some other server exports /var/mail to it, and there are a bunch of other clients that all use .lock files on that filesystem? Unlike / and /usr and /etc, which can be considered private to each machine, /var/mail is much more likely to be a global filesystem with a site-wide, not machine-specific, file locking policy and permissions. -- Rahul Dhesi <dhesi@spams.r.us.com> To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
