The options must be restricted. This is the Product Management answer to the current status of bcache tools: > - we *must not* build the tools on non_x86_64 > - we must open feature requests in JIRA for s390 > - we must open feature request for ARM and power So don't even expect bcache-tools to be available in the short term. > Fr the rest of archs, bcache devices would only be listed> but no actions > could be performed over them. Opinions? No actions allowed. That's for sure. About displaying it, that's a more complex question.
