WIP: mkinitfs: terrible hack to mount rootfs over NFS

Administrator requested to merge zhuowei:nfs-root into master

Created by: zhuowei

Very hacky proof of concept for #511 (closed): this mounts /boot and / on Nexus 6P (angler) over NFS over USB.

Do not merge this.

Changes:

  • Removed existing root/boot detection code
  • Changed mount commands to mount as NFS
  • Changed DHCP range to only give out one IP address.

I'm serving NFS using my host system (Ubuntu 14.04)'s nfs-kernel-server, and I've rebuilt my device's kernel to add NFS support. The scripts I used on the host system to start NFS is here.

The way it's currently implemented prevents mounting the root FS normally. What would be a good way to integrate this into the normal initfs? Also, can we serve NFS from inside the Alpine chroot or do we need to serve NFS from the host system?
