How does PBI handle minor library version differences then? If one package provides and uses mylib-1.3.1 and another provides and uses mylib-1.3.5, how is that distinguished as the core library level (the plain .so file)? My understanding of what Clear Linux is attempting allows this level of granularity to ensure a package (really an amalgamation of individual packages in the sense of most current unixy distros) is functional and updated as a whole.
