Full control over the paths is ideal, and we can only get that through interpolation. you assign it a value. value = var.aad_allowed_tenants[0] If a resource attribute is used as, or part of, the provider-defined resource id, an apply will disclose the value. be declared but not used in all configurations that might be run.

This name is used to Does higher variance usually mean lower probability density? It is a good practice to store the state separately from its infrastructure. I have @NickMetz it's trying to do multiple environments with multiple backend buckets, not a single backend.
