There are some background actions that the daemon takes, for example monitoring system memory, watching for file changes or cleaning up caches.
The daemon never runs any user code in the background.

There are several different types of requests, such as a request to run a set of tasks, or to query a tooling model, or to stop.

If you are not getting cache hits from the build cache, you may be using the wrong version of Java. A fixed version (Java 11) is required to get remote cache hits.

### Building a distribution from source

	// Create indicates that the lister should not attempt to load an existing cache.
	Create bool

	// Include pure directories.
	IncludeDirectories bool

	// Transient is set if the cache is transient due to an error or being a reserved bucket.
	// This means the cache metadata will not be persisted on disk.
	// A transient result will never be returned from the cache so knowing the list id is required.
	Transient bool
