… on RHEL 8 On RHEL 8, /usr/libexec/platform-python is the interpreter used by waagent and has the required modules installed. The previous logic selected python3 first, which may lack those modules, causing agent.py to fail with import errors. Moving platform-python to the top of the check order ensures AMA uses the same interpreter as waagent. Fixes Azure#2117

is it ok to check in this order for non-RHEL8 distros?

Yes — with one caveat: this changes behavior only on systems where /usr/libexec/platform-python actually exists. If that path is not present, the logic still falls through to python3 and then python2 as before
