I have changed resource pool size for small_errand from 1 to 2 and run `bosh deploy`. Before change I have run `bosh deploy` and verified that no pending changes are available (actually, then I canceled task).

I expect bosh to resize errand pool only. But before it updated health_z1 job from medum_z1 pool that was unchanged.

Can you explain this behaviour? How can I learn what changes bosh is going to implement (e.g. terraform plan)?
