Two bugs caused daemon.json to be overwritten with invalid content:
- Invalid `when` condition using unsupported Ansible inline stat syntax,
causing the existing file read to be silently skipped and docker_config
to always reset to {}
- Folded scalar `>` in set_fact converted the dict to a Python string
representation, which to_nice_json serialized as a JSON string instead
of an object
