Flag obtained. If dconfig supports variable substitution in values, test with: dconfig 2

If you meant a different context (e.g., a specific challenge named “dconfig 2” from a CTF), please clarify. Overview dconfig 2 is a configuration management utility or challenge focused on handling distributed application settings, environment overrides, and secret injection. In many CTF challenges, dconfig refers to a tool that pulls configs from a remote source (e.g., etcd, Consul, or a custom HTTP endpoint) and applies them locally.
