Mapping caps lock to ctrl in the TTY

from blog Gabe Venberg, | ↗ original
In the past 2 years or so, I have been using my caps lock key as a separate ctrl key on my desktop keyboard. This is very easy to do in X11 with a setxkmap command. However, with my laptop, I try to run without X as much as possible. (I’ve found it make a nice, distraction free environment, and it seems to be pretty good for battery life)...
