At the current time, we have migrated to activation triggers.  They are
still in each package, but it does avoid the shell snippets (and all the
related prerm+postinst scripts).

As for using a path trigger, I believe that was ruled out as they are
recursive.  The libc-bin package would have to declare an interest in
*all* of /usr/lib, which will generate tons of false-positives.  I
suspect it may also be a bit heavy on the dpkg side.

Thanks,
