Description

In the documentation about checkpointing, it is explained that you must set the config file setting `state.checkpoints.dir` to specify the directory where checkpoint metadata files will be stored.

This is no longer the case, and apparently now checkpoint metadata files are stored in the checkpoint data directory itself. This should be updated in the docs.
