"reload" doesn't appear to be recognized as a command line option with
the /sbin/service command, as seen here:

# /sbin/service privoxy reload  2> /dev/null || true
Usage: /etc/init.d/privoxy {start|stop|restart}

Does that vary between what /sbin/service is trying to reload?

This came up because I'm trying to figure out why privoxy crashes overnight
sometimes (and not at other times of the day).  It occurred to me that perhaps
some of the jiggery-pokery involved in the logrotate business might be at the
root of the issue.
