Any user who can log on at a vty can remap any key to reboot the
machine (try remapping "t" to reboot to annoy your firends ;-).
The sysctl can only be enabeled by root, so I think it would be
useful. A more useful sysctl might be one that prevented the
remapping of the keyboard unless you were root.
Last time this came up, someone shot down my argument on the grounds
that if you have access to the console you can reboot the machine
anyway. I'm not sure this holds water, 'cos having access to the
keyboard and monitor isn't the same as having access to the case/power
button/plug. However a second considered opinion here might be
useful.
