More to that.

There are 59 Makefiles that have -I${.CURDIR}/(../)+sys in them.
All these are bogus.  We should get rid of all of them (-I's).

So far, I have found sbin/mount_* use headers from /sys/miscfs/
that are not installed into /usr/include, but should be.  Where
should these be installed?  /usr/include/fs/<fs_from_miscfs> or
should we preserve the /usr/include/miscfs/ layout like in
/sys/miscfs?  Modern fs'es install their headers into include/fs
and old ones in include/<fs>.
