include

The include directive inserts (lexically) another configuration file at the current position. It is used to keep large configurations modular, reuse common fragments (e.g. logging, backends, certificates), and simplify environment‑ specific overlays.

include "fragments/aaa-policies.radconf";

Syntax

include "<path>";

Parameter	Description
`<path>`	Absolute or relative filesystem path to a configuration file. Relative paths are resolved from the directory of the file that contains the `include` directive.

Behavior

The target file is read and parsed as if its content were physically present.
Nested includes are processed depth‑first.
Order matters: earlier includes can define sections / objects referenced by later includes.
If an included file cannot be opened or parsed, configuration loading fails.
