For this last, if you managed to get a handle to one of these file descriptors using any of the associated system calls (write(), fstat(), etc.) would trigger an instant-panic. I don't think that non-root users can get to these descriptors however. -- John Baldwin _______________________________________________ svn-src-head@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"
