I propose that we move obs_decam under the lsst umbrella like obs_sdss. This entails:

• Moving it to: github.com/lsst/obs_decam
• Adding it to buildbot's build list
• Pipe dream: Use a decam image in an integration test

Our current process is not efficient: one or two people keep up with every change to the stack and learn how to incorporate those changes into obs_decam (or they fall behind and spend substantial time updating it). In contrast, it is typically straightforward for the author of the original change to duplicate the update that they make on obs_sdss.

The repository is not ready to move yet. If this proposal is adopted, we would fix up the unit test that depends on the lost testdata_decam and add some more unit tests. (The most up to date copy is under github.com/yalsayyad/obs_decam)
