Comparing the code in devspaces-theia repo (which is responsible for transforming che-theia into ds-theia) with the output in the devspaces-images repo, we see that there are duplicte copies of the src folder for theia dev, theia, and entrypoint, but the last one is not correctly synced.

Tasks:

• figure out why we have TWO copies of src folder, remove the unneeded dupe - look in ds-theia repo for build.sh and sync.sh
• figure out why the entrypoint's src folder is not updated correctly, and needed a manual sync via https://github.com/redhat-developer/devspaces-images/pull/241
• ensure that ds-theia dockerfile fragments are kept up to date and those changed propagated to midstream.
