Isn't this a basic software engineering skill? I'd expect this to be in
any agent's existing model, but okay, there's some Linux-specific aiming
in this skill (duplicated drivers, etc).

I'd still prefer that this documentation, which we don't really have
anywhere else in the tree that I'm aware of, should be in a human area,
with the skill referencing it instead of duplicating it.
