We're known to work on arm vanilla kernels but android kernel is highly modified
and I doubt if someone ever has it successfully running.

That said none of us tested it on Android and if you're interested in more
deep investigation -- this would be highly appreciated (but this is difficult
task actually).

As to error message you pointed -- looks like the kernel has no net-namespace
support in the kernel (check the kernel's .config file) or it might be
something else depending on how hard kernel is modified.
