Removing the bin/ directory is technically fine for running python apps, however it removes the ability for a user to customize this rootfs/virtualenv further with pip (you need bin/activate to enter the venv and customize it). Is this what we intend? If so, it's OK, we just tell users to build their own rootfs if they want customization.

edit: actually, having users build their own rootfs is probably preferable, as the activate script seems to hardcode the absolute path to the venv, so I'm not sure how well it would perform if moved :/ I have to think this issue through a bit and patch the rootfs build code, but this change is a-ok (modulo the commit message change as mentioned by @StefanJum ).
