I'm not a fan creating more global variables rather, but I'll it leave
to someone else to decide what's best. This change looks consistent
with its predecessor, and OK modulo a few nits below.

could this include a unit? config_keepalive_secs , I think?

Neither of these config readers ever return -1. Do you foresee this
ever happening? Or could this return void?

See comment in previous patch about ++ for boolean values.
