Marc, I seem to remember that David Greenman had some emails about issues similar to yours. Search mailing list archives for last two years or so for his name. I've yet to see any documentation for such issues but it seems that's some kind of way to make living. You're administering such boxes, you're supposed to know how to cope with those boxes, if you don't know, somebody more knowledgeable will do or take over.. that's how I see the whole issue about docs. We don't have so large boxes yet, but I'm probably facing the same problem soon. Nothing personal, just IMHO. -- Vallo Kallaste kalts@estpak.ee To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
