In the software sense, sustainable software is software that can be maintained. That means in practice not to have thousands of forks of the same piece of software (like it is done with the Linux kernel in Android). Instead, sharing as much of the same codebase and binary packages as possible across all devices just like it's done in a typical Linux distribution.
