we've parsed the config file. Makefile generation is too late if we've introduce changes to the syntax of the metafiles to warn about version skew, since we have to try to parse them and we get an parse error that's rather baffling to the user rather than a 'your config is too old, upgrade' which we should get. We have to defer doing it until after we've read the user's config file because we define machinename there. The version required to compile the kernel is encoded in Makefile.machinename. There's no real reason for this to be the case, but changing it now would introduce some logistical issues that I'd rather avoid for the moment. I intend to revisit this if we're still using config in FreeBSD 10. This also means that we cannot introduce any config metafile changes that result in a syntax error or other error for the user until 9.0 is released. Otherwise, we break the upgrade path, or at least reduce the usefulness of the error messages we generate. # This implies that the config file option mapping will need to be redone. MFC after: 3 days
