If the kernel do not support user namespace then one of the children created by nspawn parent will fail at clone(CLONE_NEWUSER) with the generic error EINVAL and without logging the error. At the same time the parent may also try to setup the user namespace and will fail with another error. To improve this, check if the kernel supports user namespace as early as possible.
