I wonder if this would be better done as part of the host startup, when it
initializes logging? We could include some simple log rotation as well.
Unfortunately, we can't use /var in that case because it won't be writable in
general, but I'm leery of dropping a world-writable file into /var anyway.

 # Load the service.
 # The launchctl command we'd like to run:
 #   launchctl load -w -S Aqua $PLIST
 # However, since we're installing as an admin, the launchctl command is run
 # as if it had a sudo prefix, which means it tries to load the service in
 # system rather than user space.
 # To launch the service in user space, we need to get the current user (using
 # ps and grepping for the loginwindow.app) and run the launchctl cmd as that
 # user (using launchctl bsexec).
 set `ps aux | grep loginwindow.app | grep -v grep`
