Portability is a shining goal for all software -- an objective since the beginning of computing through the present. And yet, it also remains illusive. We once sought to develop software "portable" between whole OSes and kernels; today, we've lost control of our build and distribution pipelines so completely that portability of a binary between two barely-different distributions of linux is considered radical and nearly impossible. Even "portability" of a binary when moving between two directories on the same host is often a trial by fire. In this talk, we will define and discuss two specific kinds of portability -- what it means to build path-agnostic libraries and what it means to support co-installable libraries -- then explore what this kind of freedom could do for us, and most importantly, practical ways to achieve these goals within existing systems.
