The last few haven't required reboots to either workaround or fix. (Replacing libc on a running system *can* be tricky; I blew a SCO box up that way once!) Some machines with long uptimes are in fairly secure places (walled-in) so they get serviced less - I've had an AIX box up 596 days, but it had *very* specific use and "couldn't" take an outage. I also used a VAX that we didn't find out could not boot until we tried. The boot params had been goofed-up about six *months* before the failure and we didn't know it until it nearly killed us... - Jy@ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
