From the "Creating a bind mount" section of mount(2) [1]: > If mountflags includes MS_BIND (available since Linux 2.4), then > perform a bind mount... > > The filesystemtype and data arguments are ignored. This commit adds support for configurations that leave the OPTIONAL type [2] unset for bind mounts. There's a related spec-example change in flight with [3], although my personal preference would be a more explicit spec for the whole mount structure [4]. [1]: http://man7.org/linux/man-pages/man2/mount.2.html [2]: https://github.com/opencontainers/runtime-spec/blame/v1.0.1/config.md#L102 [3]: https://github.com/opencontainers/runtime-spec/pull/954 [4]: https://github.com/opencontainers/runtime-spec/pull/771 Signed-off-by: W.
