This document covers policies that may be configured for reacting to component termination.
A component that has the “reboot-on-terminate” policy set will cause the system to gracefully reboot if the component terminates for any reason (including successful exit). This is a special feature intended for use only by system components deemed critical to the system's function. Therefore, its use is governed by a security policy allowlist.
If you believe you need this option, please reach out to the Component Framework team first.
To enable the feature, mark the child as on_terminate: reboot
in the parent component's manifest:
// core.cml { children: [ ... { name: "system-update-checker", url: "fuchsia-pkg://fuchsia.com/system-update-checker#meta/system-update-checker.cm", startup: "eager", on_terminate: "reboot", }, ], }
Also, you‘ll need to add the component’s moniker to component manager's security policy allowlist at //src/security/policy/component_manager_policy.json5
:
// //src/security/policy/component_manager_policy.json5 { security_policy: { ... child_policy: { reboot_on_terminate: [ ... "/core/system-update-checker", ], }, }, }
