Hello,

I have writte the following to check that each partition on a device of a certain type has a uuid (N.B. extended partitions used in logical partitioning scheme do not):

- set\_fact:  
partitions: “{{ partitions|default() + [item.value.partitions] }}”  
with\_dict: “{{ ansible\_devices }}”  
when: item.key is regex(“^sd[a-z]”)

- assert:  
that: item.value.uuid is not none  
with\_dict: “{{ partitions }}”

Is it possibe to combine these two tasks into one task? It looks like it should be possible using with\_subelements but that looks like it is designed to work with lists of dictionaries rather than nested dictionaries. I’ve also tried and failed with with\_nested.

Thanks
