There's new utilities tarball out there. The mconsole client now has the

uml_net now is as helpful for TUN/TAP as for ethertap. It is willing to
create /dev/net and /dev/net/tun and to insmod the tun module.
It also insmods netlink_dev for ethertap. I'd appreciate it if people who
currently are insmoding netlink_dev by hand would check this and make sure
