The Go runtime provides a number of configuration knobs that subtly change its behavior, and we cannot control which of these is available over time as we change which version of Go we're building with. It's therefore possible that an OpenTofu user might be intentionally or unintentionally relying on one of these settings for OpenTofu to work on their system, in which case they would be broken if they upgraded to a newer version of OpenTofu which uses a different Go version that no longer supports that setting. These log lines are intended to help us more quickly notice that possibility if someone opens a bug report describing an unexpected behavior change after upgrading to a new OpenTofu minor release series. We can ask the reporter to share "TF_LOG=debug" output from both the previous and new releases to compare, and then these log lines should appear in the older version's output so we can search the Go codebase and issue tracker for each of the mentioned names to learn if the handling of that setting has changed between Go versions.

OpenTofu
OpenTofu is an OSS tool for building, changing, and versioning infrastructure safely and efficiently. OpenTofu can manage existing and popular service providers as well as custom in-house solutions.
The key features of OpenTofu are:
-
Infrastructure as Code: Infrastructure is described using a high-level configuration syntax. This allows a blueprint of your datacenter to be versioned and treated as you would any other code. Additionally, infrastructure can be shared and re-used.
-
Execution Plans: OpenTofu has a "planning" step where it generates an execution plan. The execution plan shows what OpenTofu will do when you call apply. This lets you avoid any surprises when OpenTofu manipulates infrastructure.
-
Resource Graph: OpenTofu builds a graph of all your resources, and parallelizes the creation and modification of any non-dependent resources. Because of this, OpenTofu builds infrastructure as efficiently as possible, and operators get insight into dependencies in their infrastructure.
-
Change Automation: Complex changesets can be applied to your infrastructure with minimal human interaction. With the previously mentioned execution plan and resource graph, you know exactly what OpenTofu will change and in what order, avoiding many possible human errors.
