What the developer wrote
Authored by Niklas Dusenlund
Dockerfile: Use `python3` executable.
Python should be invoked as `python3` since we are writing python3 code
and not python2. See https://peps.python.org/pep-0394/#recommendation
Many (most?) distributions do not distribute a "python" executable any
more, forcing you to pick either 2 or 3.
What changed, and why it matters
This commit is a routine build/maintenance change. It updates two helper scripts to explicitly call Python 3 instead of relying on a system default 'python' command, and removes a Dockerfile step that forced 'python' to point to Python 3. There is no security-relevant change to the firmware or its behavior.
No security action required. Treat as normal build-system maintenance.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The patch changes the shebang of scripts/expand_template and scripts/get_version from ‘#!/usr/bin/env python’ to ‘#!/usr/bin/env python3’. It also removes the Dockerfile instruction ‘update-alternatives –install /usr/bin/python python /usr/bin/python3 1’ and bumps the container version. These are compatibility/build-hygiene changes only; no code logic, cryptography, or device-facing behavior is modified.
