Well, Ansibles variable system isn't as featureful as e.g. hiera and
works mostly with overwrites.
I see two possibilities here:
1. Using the a lookup plugin, not inventory variables, e.g. hiera since
it supports all kinds of merging
https://docs.ansible.com/ansible/latest/plugins/lookup/hiera.html
2. Use a different name for the variables and use set_fact in your
playbook/a role to merge them.

[ansible-project] add list from host variables and group variables
Hi, this is what I have in a YAML formatted inventory --- all: vars: city: - Berlin children: g_empty: hosts: emptybuster: emptysid: emptystretch: city: - Steglitz With this code, I get "city": [ "Berlin" ] for emptybuster and emptystretch, and "city": [ "Steglitz" ] for emptystretch. I would, for some reason, have "city": [ "Berlin", "Steglitz" ] instead. I have searched on the web and found a collection of wild constructions involving filters and/or set_fact, none of which yields the desired result. I have thought about setting hash_behavior=merge and making the city list a hash instead, but setting hash_behavior=merge is not recommended. Is there a more elegant way to do this, or have I reached ansible's limits? If so, is there a bug report against ansible where I could read up on the situation?
