6.3-PRERELEASEからRELENG_7へうまくあげられないorz
カーネルmakeの部分でconfigが古いんだよ！と拒否されてしまった。
RELEASEが出たら直るかなあ・・・

こんな感じ
/usr/obj/usr/src/usr.sbin/config/config GENERIC
ERROR: version of config(8) does not match kernel!
config version = 600003, version required = 600004

Make sure that /usr/src/usr.sbin/config is in sync
with your /usr/src/sys and install a new config binary
before trying this again.

If running the new config fails check your config
file against the GENERIC or LINT config files for
changes in config syntax, or option/device naming
conventions
