Unfortunately, you can't just extract just a couple of values (ATM),
you'd have to reload all the configuration (when the tool starts, it
does --get to the backend, getting the whole XML), so you could make
something like:

tool->config = gst_tool_run_directive (tool, NULL, "get", NULL);

But this would replace any change done with the old config, so you might
do 2 things:

1) Store the possibly modified config in an auxiliar xmlDocPtr for
mixing both of them after installing the package
2) Just update the "smbinstalled" tag with gst_xml_element_set_boolean()
if you know whether it was installed correctly :)

I'm very sorry that there isn't a better method for doing this, I'm
already working in a solution
