Less disk access at startup, or in general somehow? Optimizing for startup
performance over general performance does not seem so good. But this is
really about elegance rather than resource usage, right?

Currently, /var/run and /var/lock on my rawhide desktop system take up 364K.
385K on another rawhide system. (Blocksize of 4k.) I think we can spare that
in this day and age if we get a reasonable benefit in return.

Meanwhile, NetworkManager is doing absolutely nothing for me, and is taking
up a USS of 65.3M. If we're gonna tilt at memory consumption windmills, how
about we take a look at that one?

(NetworkManager is awesome on my _laptop_, by the way. Wouldn't dream of
living without it.)
