Hi Bill,

~From what I've read, you have to take some extra steps to get this to
work.  First, visit this page and search for "suiddir":

http://www.freebsd.org/cgi/man.cgi?query=mount&sektion=8&apropos=0&manpath=FreeBSD+7.0-RELEASE

I believe you have to run a kernel with the SUIDDIR option enabled, and
then you have to mount your filesystem with the suiddir option, as
described in the mount man page above.

Let us know if that works for you or not.

Best regards,
Greg
