As I said, I was a little unclear on what you were ultimately trying
to do.

I assume you are making a change to one of the signal.h files and
want to propagate that change out to the export and obj trees without
doing a complete rebuild of everything that depends on signal.h.  I
haven't tested out the export_signal.h rule, but I would expect it to
do something to the export tree in the 3 marked Makefiles.  I don't
believe these Makefiles will populate the obj tree (particularly
usr/sys/include/...) with that rule.  Nothing in the build should
depend on something in the obj tree, but the files in the obj tree --
not the ones in the export tree -- are the ones that the install step
eventually places on the result disk.  Updating just the export tree
might be all you need to do...but I would probably want all the copies
of signal.h to be updated after the change.

As to the last part, when I looked at the export tree, I saw it
contained no usr/sys directory.  This is the location used when the
customer rebuilds the system after installation but is not used by our
build procedures.
