Since the architecture-specific lib32z1, lib64z1, and libn32z1 packages
are basically “alternatives” to zlib1g, I suppose we could game the
system and add --add-udeb=zlib1g-udeb on their dh_makeshlibs call. It
doesn't look or feel clean to me, but it'd be an obvious and direct
improvement over the current situation.
In the amd64 case, the above shlibs becomes:
(unstable-amd64-devel)kibi@tokyo:/tmp/zlib-1.3.dfsg+really1.3.2$ cat
./debian/lib32z1/DEBIAN/shlibs
libz 1 lib32z1 (>= 1:1.2.3.3.dfsg-1)
udeb: libz 1 zlib1g-udeb (>= 1:1.2.3.3.dfsg-1)
and dependencies look better:
Depends: libc6-udeb (>= 2.42)
Attached patch tested on amd64.
Cheers,
