Of course, mount all file systems on the disks nosuid,nodev before doing this, and do not forget to update fstab(5). * In /etc/security, comment out the paragraph below # Make backups of the labels for any mounted disks * Check that /mnt does not appear in the path to the home directory of any user on the system, as security(8) checks some special files in home directories. I'm not guaranteeing this will suffice, but i hope so. Alternatively, consider simply unmounting the disks in the first place. Why have them mounted when you don't want access to them? It is not recommended to disable security(8) and probably not needed for your purpose. I'm not discussing which non-default features you might have switched on that might be causing additional disk access. Several exist. Yours, Ingo
