Right, so far. > Is it safe ? It's not completely safe. Of course, neither is running a two-and-a-half year-old release of any operating system connected to the Internet.

There certainly are some changes. Some of them are related to important security fixes.

Well, the safest approach is to have a spare system, and build the modifications on that. If you can't do that, then almost as safe (and actually safer from your own oversights) is to have a spare machine to try out the upgrade on so you get used to the procedure. If you really can't spare a machine for any of these things, accept some downtime and make sure you're *very* careful as you go through the documented procedure. > Please, advice if you have some know-how :-))) All of my specific advice is *in* the Handbook. If I had any more advice, I'd submit it to, well, the Handbook. Good luck. _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
