It seems there is no interest in fixing bugs (such as [1]). Moreover, same guest filesystem (same host os, distribution, etc.) on two different machines (i7-2630 the first, i7-7700HQ the second) yield different results, with crashes and corruption of filesystem in the modern computer. So, can I consider UML as a legacy thing in the Linux kernel? With what I can replace it (I'm doing TCP research, and I focus on the networking stack)?
