    SubjectRe: How come dd if=/dev/zero of=/nfs/dev/null does not send packets over the network?

    As far as I understand devices in Linux, device file is only some kind of
    note to the *local* kernel that operations on that file is to be
    redirected to the device. It is always resolved by the local kernel and
    redirected to the local device (if tere is driver that claims this
    major/minor number). Life would be to simple...
