Use BuildRoot to create a custom Linux + BusyBox distro for the browser

[humphd]

Let's use buildroot to create a stripped down Linux Kernel and BusyBox command set. Ideally we'd get rid of everything we can't/won't use to save space.

I will need the following Kernel Modules for 9Pfs sharing:

CONFIG_NET_9P=y
CONFIG_NET_9P_VIRTIO=y
CONFIG_NET_9P_DEBUG=y
CONFIG_VIRTIO=y
CONFIG_VIRTIO_PCI=y
CONFIG_9P_FS=y
CONFIG_9P_FSCACHE=y
CONFIG_9P_FS_POSIX_ACL=y

There's another example Dockerfile you can look at, from someone who did a similar thing:

57 is related to this, to help with the case of doing this on Windows.

Another thing we'll need, is terminal access on the first serial port, ttyS0, perhaps this in inittab:

ttyS0::respawn:/sbin/rungetty ttyS0 --autologin root

I've done this now, and it's landed.
