The shared stack on lsst-dev provided in DM-5435 does not contain the obs_cfht or obs_decam camera packages. Please add them.
Provide a shared stack on lsst-dev & other relevant systems
Please provide weekly & release tags of obs_*
Although DM-5661 isn't marked as done, as of DM-8256 we're including the lsst_obs package in weeklies and hence bringing in obs_cfht and obs_decam when we install the shared stack. Mission accomplished.
