Comment (by danielluke):

 - bind9 port shouldn't overwrite named.conf, it only installs a
 named.conf.dist file
 - dlopen stuff is only set for old platforms (which I don't actively test
 on), I rely on people who use those old/unsupported platforms to test and
 submit changes. If we need to remove those config options, we can.
 - lock file is a config option:

 lock-file (I don't have it set on my install, YMMV).
