The utility that calls mount would not allow a disk with setuid root executables on it. Since the Amiga knows when a floppy is ejected, it should be possible to note such action and unmount the filesystem upon ejecting the disk. This would preclude mounting-and-swapping to get around security. -- _. --Steve ._||__ Warren v\ *| V
