It seems that > the pseudo-MIB scheme of sysctl is nice. Personally, I like the basic idea (unified hierarchical namespace, method-based access, etc), but sysctl (and kernfs') implementation is unpleasantly inflexible. I also agree with Garrett that the filesystem metaphor isn't half bad when it comes to at least basic access control for parameters, and this is where either the Linux or NetBSD approaches lead the way. I'm also swayed in that we *do* need to follow the Linux lead at least to the point where we can run their binaries with a reasonable degree of success, so there's a little pressure on the border. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
