I was thinking we would need a file trigger per service, which is
activated automatically (requires changing all service packages);
or an explicit trigger, which is activated by each library postinst
(requires changing all library packages).
Are you suggesting a file trigger on /lib and /usr/lib? It seems
inefficient as I think the triggered postinst would have to check
*all* libraries, but I suppose it would work. And presumably this is
no worse than what checkrestart does now.
