```
TORRUST_TRACKER_BACK_           -> TORRUST_TRACKER_
TORRUST_TRACKER_DATABASE_DRIVER -> TORRUST_TRACKER_CONFIG_OVERRIDE_DB_DRIVER
TORRUST_TRACKER_API_ADMIN_TOKEN -> TORRUST_TRACKER_CONFIG_OVERRIDE_HTTP_API__ACCESS_TOKENS__ADMIN
TORRUST_TRACKER_CONFIG          -> TORRUST_TRACKER_CONFIG_TOML
TORRUST_TRACKER_PATH_CONFIG     -> TORRUST_TRACKER_CONFIG_TOML_PATH
```
