- Switched from dbus-rs to a native dbus implementation see [#2208](https://github.com/containers/youki/issues/2208) for motivation behind this. This replaces the `dbus` module with `dbus_native` module. However, As this is not in public interface for the crate, the users of this crate should not need any code changes. As this removes the dependency on the `libdbus` system library, you can uninstall it if desired.
- The `Rootless` struct has been re-named as `UserNamespaceConfig` , `RootlessIDMapper` has been re-named to `UserNamespaceIDMapper` , and correspondingly the `RootlessError` has been re-named to `UserNamespaceError` . This is due to the fact that the structure was to be used for containers when a new user namespace is to be created, and that is not strictly only for rootless uses. Accordingly, the fields of various structs has been updated to reflect this change :
- Executor now contains 2 methods for implementation. We introduce a `validate` step in addition to execute. The `validate` should validate the input OCI spec. The step runs after all the namespaces are entered and rootfs is pivoted.
- Executor is now composible instead of an array of executor. To implement multiple executor, create a new executor that runs all the executor. The users are now in control of how multiple executor are run.
