And that’s a perfectly good solution that I like.
Personally, I think people should forget that /usr/bin/python exists: the
recommendation from Python is to call python2 or python3. I can quote from
PEP-0394:
“””
Depending on a distribution or system configuration, python may or may not be
installed. If python is installed its target interpreter may refer to python2
or python3.”
…
• Distributors may choose to set the behavior of the python command as
follows:
• python2,
• python3,
• not provide python command,
• allow python to be configurable by an end user or a system
administrator.
“””
We’ve picked option 3. As per Python upstream, that’s absolutely fine.
If you have a serious need that /usr/bin/python exists, and is a symlink to
python3, then could you not make a simple recipe that RDEPENDS on python3 and
ships just a /usr/bin/python -> python3 symlink? You can even put this in your
layer to avoid having to debate it with the oe-core maintainers.
