I see that HEAT can patch multiple *NIX OS distributions.
Do all Red Hat/Solaris etc servers require a valid support subscription with the vendor as a prerequisite to HEAT?
How does HEAT collate Errata/CVE for each server?
For Red Hat/Solaris yes just require valid subscription with the vendor.
HEAT collect require Patch on each server by using PatchLink agent that install on *nix system.
