## [Unreleased]
### Breaking
- runc update no longer allows `--l3-cache-schema` or `--mem-bw-schema` if
`linux.intelRdt` was not present in the container’s original `config.json`.
Without `linux.intelRdt` no CLOS (resctrl group) is created at container
creation, so it is not possible to apply the updated options with `runc
update`.
Previously, this scenario did not work as expected. The `runc update` would
create a new CLOS but fail to apply the schema, move only the init process
(omitting children) to the new group, and leave the CLOS orphaned after
container exit. (#4827)
