Unless i'm mistaken (and i very well might be), a 'random' user
couldn't use an old mountd to crash the kernel.  mountd is command
used by root, and only by root.

If my assertion above is true (and again, it might not be; i've not
tried it), then couldn't such a cracker cause more disruption by using
the 'halt' command?

i mean, the system reboots after a panic...
