Sun usually pointed you at the appropriate megapatch after that, though.

You may not know - I did. Even things that were only read at startup could generally be dealt with by restarting just the process that read that. Of course, if that process was the kernel or init, you wound up rebooting anyway. And in some cases, the chain of things that depended on that change was complex enough that rebooting was simpler. In any case, I'm paranoid enough that I always rebooted after a patch that touched the system startup code, just so I wouldn't find out that the system startup was now broken when someone rebooted it during my vacation. For yet another difference - not even Sun recommends installing *every* fix. FreeBSD doesn't have any other option. Note that I'm *not* proposing such a system for FreeBSD! Merely pointing out that the differences is very noticable. <mike To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
