This raises a can of worms when maintaining the program, and the
question arises as to which is the "real one". I'm likely to forget
to update one or the other. "Which one do I enter into version
control?" is a question I would ask myself often.
Where are SELinux attributes stored? In the inode? If not, can hard
links be given different attributes?

Well, that may be more managable in the long term. Can you suggest a
(relatively) simple way of doing that?

This sounds like a bug. A user executing a httpd script should not be
changing context to httpd_sys_script_t, correct?
