salt: Python 2.7 provided via Salt repo breaks RHEL6 satellite badly

Description of Issue/Question

RHEL6 Satellite 5.6 uses python to work, but its scripts reply on python 2.6.6. When I upgraded Salt to a 2017 version it also installed Python 2.7 from the salt repo this broke the upgrade scripts for Satellite so the server is un-upgradeable. The fix is to un-install salt 2017 and Python2.7 at least I hope so I am currently trying to recover Satellite 😦

I would consider this a rather serious oopise on salt’s part. Its fine to install a later python but this should not supersede the OSes requirements/dependencies and break the functionality or other products / applications in the process.
