We're not currently using virtualenv during make. But we should, at least for tox -e flake8. I think removing the build dependency to virtualenv would go in the wrong direction. If anything we'll need virtualenv more and more moving foward. Not less and less.

I'm not saying to remove the dependency; I'm saying that it's not necessary outside the test build.

(and even more so that it runs every build, whether anything's changed or not)

I think we should run flake8 on build.

I would support that enhancement

It's fine to run flake8 on build, but can we not use tox or a virtualenv, and use python-flake8 from the distro instead?

That would reduce the complexity of the build considerably.

It is not necessary to install tox to run flake8. This can easily be done with the flake8 system package.

Running virtualenv everywhere every time is a burden
