Thanks, @jerome. I recall verifying this manually with jsonschema, but probably that test did not caught everything.

Thanks @kirr We have an extra test in this test suite which also checks the indentation ( https://lab.nexedi.com/nexedi/slapos/blob/08615bc50b7de675bfeb2bf9850d195180f357fd/slapos/test/test_json_schema.py#L79-92 ). I guess using jsonschema only checked for the syntax

@jerome, thanks for explaining. And from that test I see we also have format-json which is useful to bring json/schema into canonical form (to which you already reffered in the commit title).
