If the patches are applied to a loadable kernel module only, then it should (at least in theory) be enough to rebuild/install the kernel as usual and then just reload the kernel module instead of rebooting. Reloading the module requires that the given service is not in use, which is why it may be easier to just reboot. Taking this idea to the extreme, there is a number of other projects, non-FBSD, that work on micro/nanokernel technology. I can't recommend you one over another - I haven't tried them - QNX is a commercial product, also there is open-source LSE/OS, just to get you started.

As others have said, no, and it's not really important, though FWIW, my uptime is always as long as my machines run without me rebooting them, meaning they'll stay up until I say otherwise ;) They never go down on their own. I have a laptop running close to a month now, and the only reason it's not longer is because I wanted to update to 5.4-PR. But ... rebooting in order to update for security fixes is not a bad thing.

It depends very much on what you're doing with it and what the vulnerabilities are. Security is always a balance between practicality and safety. FreeBSD is very secure by design, but ignoring security updates isn't necessarily the best idea. If I were running 3.x, it would probably make me a bit nervous if I couldn't update it to at least 4.11, though some people still do run 3.x - wouldn't necessarily recommend it, though. - jt ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Of course this does not make much sense and the customer in question
would be well advised with an update. Have been talking to them.
Our own production servers regularly reach 200 days and more. We update things
like ssh and openssl in place and only do full buildworld/installworld
upgrades perhaps once or twice a year. Lot's can be done while staying up.
Jails help a lot of course. Not having external users with shell access also
helps.

It's rather pointless to go beyond this time, since it means you're running seriously out-of-date software. I suspect that the predominance of BSD/OS in the top positions is due to the fact that it costs money, whereas FreeBSD users are more likely to update. Note that the current top of the list has been running for 1741 days, which means that it was booted in May 1999. A lot has happened in that time. What I find more interesting is a thing that people can relate to more directly: how long has you *desktop* been up?
