This, however, requires that:
(a) the kernel be configured and built to support the Magic SysRq Key
(b) the system be configured to turn Magic SysRq on (usually an init script option)
It seems more and more distro's are at least enabling SysRq in their kernels, but leaving it disabled at system start time.
Besides, enabling Alt-SysRq+k also enables Alt-SysRq+b. Do we really want the ability to have anyone soft-reboot the system without so much as a sync & unmount (Alt-SysRq+s and +u, I think)?
To me, it seems that Alt-SysRq, all by itself, would make a great "system attention" key sequence. Why? Because it's the "System Request" key.
