-{# NOTE(kevko):
-  In all distros, there is always a /usr/bin/python3 -> python3.X.
-  However, this is disrupted for RHEL-based systems because, unlike
-  other distros, we upgrade Python above [1], but we forget to set
-  the default python3 to the new python3.X. As a result also, everything
-  outside of the virtual environment ends up running on Python 3.9.
-
-  So, let's correctly set python3 -> python3.X since we had to install
-  it and now have default python3 points to the new version.
