Re: [MirageOS-devel] /dev/net/tun on Cubieboard2

[Luke Dunstan <lukedunstan81@xxxxxxxxx>]

If the image was the one downloaded from openmirage.org, then it was
built using these scripts: https://github.com/mirage/xen-arm-builder

If you want to change the kernel config and rebuild it then you should
be able to just do the kernel step manually without rebuilding the
whole image.

If you are using that image though, you'll probably find it more
interesting to use Xen rather than Unix+tuntap.
