pub const HANDOFF_INIT_AUTO: &str = "auto";Expand description
Sentinel value for ENV_HANDOFF_INIT requesting auto-detection.
When the env var matches this exact string, agentd probes
HANDOFF_INIT_AUTO_CANDIDATES in order and uses the first path
that exists and is executable. If none match, boot fails with a
clear error in kernel.log listing the paths it checked.
