Furthermore, if it asked about the system requirements of all Ubuntu-based systems (official or not), it would not be off-topic on a site like
Unix & Linux, but it would be
too broad even on such a site, because that's a huge number of systems and the question doesn't specify any specific use case. I voted to delete your answer because, although it was well-intended and the information it provided may have been useful in some other context, it was not really answering the question that was asked.
