Consider : A linux application calls gethostid() in the Linux C library. _This_ funtion then makes the SIOmumbleHWADDR ioctl call to get the ether hardware address. The kernel 'hostid' variable is too short for the ether address, and the ether address _is_ visible inside the kernel (if one exists).
