This package appears to modify /etc/ld.so.conf and does not appear to be part of libc. Packages installing shared libraries in non-standard locations were previously permitted to modify /etc/ld.so.conf to add the non-standard path, but this permission was removed in Policy 3.8.3.

Packages containing shared libraries should either install them into /usr/lib or should require binaries built against them to set RPATH to find the library at run-time. Installing libraries in a different directory and modifying the run-time linker path is equivalent to installing them into /usr/lib except now conflicting library packages may cause random segfaults and difficult-to-debug problems instead of conflicts in the package manager.
