He said: | How do we ensure that someone upgrading a package from potato to woody | pulls in all of the required libraries?

In potato, libbar does not | declare a dependency upon libbaz, although it will in woody. However, this is untrue: If libbar is built with debhelper, the potato version already has the dependancy on libbaz, since debhelper already ran dpkg-shlibdeps on libbar.so. Julian's idea to use the shlibs file seems uncalled for in this case. | Now the user decides that they wish to install foo, for some reason | they choose to install the unstable foo. Now they will need to | install libbar to fulfill foo's dependencies, but the potato libbar | doesn't depend upon libbaz. -- see shy jo
