See chflags(1) -- /var/empty has had the 'schg' flag applied to it to
make it immutable.  You can see that by:

    % ls -ldo /var/empty
    dr-xr-xr-x  2 root  wheel  schg 512 Jun 25  2002 /var/empty/

Now, to get rid of the schg (or any other) flag you need to run:

    # chflags -R 0 /var/empty

however that will only work at a low securelevel.  If you have raised
the securelevel -- ie if:

    # sysctl kern.securelevel

tells you securelevel is anything other than '-1' or '0' then you will
need to reboot the system into single user mode in order to do that.

    http://www.freebsd.org/doc/en_US.ISO8859-1/books/faq/security.html#SECURELEVEL

Also see init(8) where the details of securelevel settings are
described.

	Cheers,
