From: http://www.freebsd.org/cgi/man.cgi?query=mount&sektion=8&apropos=0&manpath=FreeBSD+5.2-RELEASE+and+Ports A directory on the mounted file system will respond to the SUID bit being set, by setting the owner of any new files to be the same as the owner of the directory. New directories will inherit the bit from their parents. Execute bits are removed from the file, and it will not be given to root. Note the last sentence. The below patch is acceptable to me.
