First, let&#x27;s put aside the start of the blog post, which consists entirely of empirical questions. Each potential adopter of unikernels will have to figure out for themselves wether their specific use-case justifies the cost and benefit of this particular technology, just like all others.<p>Putting that aside, debuggability is an obvious and pressing issue to production use-cases. Any proponent of unikernels that denies that should be defenestrated. I haven&#x27;t come across any that do.<p>How to go about debugging unikernels is unclear because it certainly is still early days. However, I don&#x27;t think the lack of a command-line in principle precludes debuggability, nor does it my mind even preclude using some of the traditional tools that people use today. For example, I could imagine a unikernel library that you could link against that would allow for remote dtrace sessions. Once you have that, you can start rebuilding your toolchain.<p>P.S. Bryan, where&#x27;s my t-shirt?
