The problem here is that I haven't found a reliable way of determining
where hal addons/callouts go. Obviously _I_ know where they go :) but
configure doesn't.

libexec is the closest approximation

hal-dccm and synce-serial-chat are true libexec, so on debian go
in /usr/lib/<packagename>, ie /usr/lib/synce-hal. They are only called
internally so the exact location is not vital.

hal-synce-* are the problem, they go in the hal addon location, which is
poorly defined. On debian it's the hal libexecdir, ie /usr/lib/hal.

Your understanding of how the process works is correct, everything
initially comes from hal, so runs as root anyway.
