Hi I'd like to define a group in my inventory that will include hosts as well as some groups. For instance I have this in my inventory: [squid] proxy-prod proxy-uat proxy-test [testgroup] squid extrahost If I run a playbook and use 'testgroup' for the hosts definition, I get: [WARNING]: Found both group and host with same name: squid If I change the inventory to use the children syntax: [testgroup:children] squid extrahost Then I get: [testgroup:children] includes undefined group: extrahost I can get this to work outside of the inventory, in my playbook:   hosts:     - squid     - eventr-uat But then this collection of hosts isn't available in the inventory, and hence not to other roles etc. Is it possible at all to have a 'mixed' group in the inventory? Thanks Dick ---

This should work [squid] proxy-prod proxy-uat proxy-test [testgroup] extrahost [testgroup:children] squid
