i don't understand why the chmod made `windoz' world writable instead of floppy... unless it already was and your point is that chmod is not working on floppy. is a msdos filesystem mounted on floppy/ ? if so that is why. msdos does not have any concept of file permissions, you cannot change the faked ones the kernel enforces with chmod. instead you need to do: mount -t msdos -o uid=1000,noexec /dev/fd0 /floppy which will cause all files on the msdos filesystem to be owned by uid 1000 (most likely you, do a `getent passwd yourusername' to see what your uid is) note that changing permissions on the mountpoint directory when nothing is mounted does nothing but open security holes. permissions on the mountpoint have no effect on any filesystem mounted on top. -- Ethan Benson http://www.alaska.net/~erbenson/
