Review comment:
`edge` and `mid` are split now in 884ea728cb because GitHub Actions
apparently doesn't support single-file bind mounts.
In order to do that, `edge`'s `/opt/init.d/99-run.sh` came from
`edge/run.sh` and `mid`'s `/opt/init.d/99-run.sh` came from `mid/run.sh`, so,
without attempting to reconcile those 2 scripts, it just meant 2 separate
images.
The
```dockerfile
COPY infrastructure/cdn-in-a-box/edge/init.d/ /opt/init.d/
```
layer is essentially at the end of the Dockerfiles anyway, so the other
layers are still cached.
