SysRq (Magic SysRq key)

Also, we’d use them as as inspiration (like from any source
anyway), and then independently verify all claims (before we make
changes on our side) not for face value.

Of course, but we shouldn’t be too trusting of Copperhead.

When the whole machine appears frozen Ctrl + C won’t have any effect. sysrq might work.

If Ctrl + C doesn’t work, I doubt sysrq would.
