We put the s2i scripts at /usr/local/s2i. The norm (and default path for the s2i binary) appears to be /usr/libexec/s2i. We should consider migrating to that so we're less unusual. As an intermediary step we should add a compat symlink from one to the other. If we move the path, we should add a compat symlink in the other direction for a time as well (and update the container metadata/labels)
