Shouldn't python3-venv then be better included in the base image, then installing it manually in the build workflow?

It will already be in all future base images by the change in build/pkgs/python3/distros/debian.txt

Replying to @mkoeppe:

It will already be in all future base images by the change in build/pkgs/python3/distros/debian.txt

Okay, then why add it manually in the build workflow? For testing purposes this is fine, but I guess it should be removed before merging this ticket.

It's a no-op in the future and we can remove it in a later ticket, but not now because I want to use it for the tests of all the tickets that depend on it.

Makes sense. Then I would propose to squash the current commits and remove python3-venv from the build workflow in a new commit. Then you could cherry pick the squashed commit in other tickets that depend on this one here.

Or at least add a comment in the workflow that it should be removed in the future.

Otherwise this looks good to me.
