That's my understanding. It should be possible to override, but not to merge. I don't know if the jsonpatch merging works differently but I suspect it doesn't.

That makes total sense, thanks for the insight! So essentially there currently is no way then to merge userdata with vendordata. Does that sound correct?

I'm currently trying to figure out how to prevent userdata from overwriting vendordata. I was under the impression that specifying merge_how for _both_ userdata and vendordata might be the solution, but in my testing I am not seeing this. Userdata - /var/lib/cloud/instance/user-data.txt =========================== #cloud-config merge_how: - name: list settings: [append] - name: dict settings: [no_replace, recurse_list] runcmd: - echo hello world from user > /run/hello_world_user Vendordata - /var/lib/cloud/instance/vendor-data.txt =========================== #cloud-config merge_how: - name: list settings: [append] - name: dict settings: [no_replace, recurse_list] runcmd: - echo hello world from vendor > /run/hello_world_vendor I would expect the existence of _both_ files, /run/hello_world_user and /run/hello_world_vendor. But only /run/hello_world_user exists. Am I doing something wrong? If merge_how isn't the way to merge vendordata and userdata, is there another way? Thank you in advance!
