Newbie - Inventory Query

Hi all

Can Ansible AWX 4.0.0 (inc Ansible 2.8.0) source inventory from Spacewalk 2.8 (Red Hat Satellite 5)?

Within INVENTORIES → test → SOURCES → CREATE INVENTORY SOURCE, the SOURCE drop-down list only contains Red Hat Satellite 6 (which is the downstream version of Katello/Foreman, not Spacewalk)?

If not, has anyone found an alternative way of sourcing inventory/node data from Spacewalk?

Regards
Phil
