Attribute unique in XML metadata (-o metadata) is set to TRUE (1) by default in all of the cases. "Unique" should be used only in situation where same value cannot be used across several agents. Fence agents do not have such kind of attributes so default value should be FALSE (0).
Fixed in upstream:
I looked through the metadata generated by all fence agents and found the following agents still produce unique parameters
Should these fence agents be fixed too?
