You definitely don't want to interrupt a running system and it finding some idle time for service gets really difficult. However, even with the Linux project, one cannot keep his processes running... Would be nice if you could upgrade subsystems one at a time. This way one could, for example, shutdown the network subsystem, load the new version and restart it. Just a thought. And uptimes are not important. Downtimes *are*. -- Nimrod. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
