I'd suggest changing that to permissive until you get things working, but
that's probably not your problem.

Not sure I understand your comment. Are you saying you are building a
version 22 policy even though this is set to 18?

That means checkpolicy generates 22 if nothing is specified and is capable
of generating policies between versions 15 and 22. That doesn't mean the
policy build when you type make will be 22, as the Makefile uses the
OUTPUT_POLICY setting to determine what to build.

OK. Sounds like a great goal. Sorry for questioning you motives. I'm used to
getting questions from people who think they can type make install and have
a functioning enforcing system despite the fact that no one has done the
work you're talking about doing.
Regardless, none of this seems to be a problem. I assume when you ls -alZ /
you see that / is default_t, but nothing else is? What happens when you try
restorecon -v / ; ls -alZ /
