IMO, lintian should take this in two steps. One, anything not in /lib or
/usr/lib, that is a DSO, better be a module or plugin. The check for
this is something that adds the file to /etc/ld.so.conf, in which case
(and this may be hard to check as-is), the package is setting up a
subdir (a la /usr/i486-linux/lib or /usr/X11R6/lib) where DSO's will
live, and will be recognized by ldconfig/ld.so.
You're right, this needs to be in policy, and a decent interface for
making changes to ld.so.conf needs to be added (maybe I can do that in
libc6) so that packages can call that script, and lintian can check for
it.
