Adding an 'unmount #e' to your namespace file will remove access to #e as is. However I want to look a bit more at doing the inverse operation, so you could say something like "permit #e #| #p" and have it block all non listed devices in the namespace file. I think that is more useful to think about and avoids 10 lines of manually selecting drivers to shoot. Perhaps a new /lib/namespace.service could become the default for networked services. Either way, with the kernel modifications passing the sniff test, I will spend some time seeing how to integrate this change in to existing daemons. Thanks, moody
