From 4bc2b0b76d0257c828db84a98400d7000aa6568a Mon Sep 17 00:00:00 2001 From: Warner Losh Date: Tue, 27 Apr 2010 06:14:30 +0000 Subject: Require the option that's mapped be listed in the options file. This will allow people with old config options to either have it just work (if config is new enough), or get a version error (if their config is about 7.0 or newer) rather than getting a cryptic error about duplicated options in the options file, or getting an error about an unknown option, at which point they'd update their config file only to learn they need a new config, only to learn they didn't really need to update their config file... All this because our version checking was in the wrong place for the past decade... # hopefully this is the last change, and we'll be able to config with an # 8.0 GENERIC file on stable/8 after I merge this change and add the # compat options.
