pi-zero image differs from pi3 and pi4 images

[robmarkcole]

As title, I've sent an email to support. In summary on pi-zero:

1. SSH is not enabled
2. all_models directory is not present

Hi, thanks for pointing that out. Indeed, the pi-zero setup is older, I don't yet have a pi0 version of the 2.11.2 API version, so necessarily the images differ - that's wai.
However the two specific issues you pointed out can be fixed - i updated the pi0 image accordingly for better consistency with the newer images. Note though that several differences remain, which cannot be reconciled.
