Containers that are meant to be booted from do not need the initLayer. The default init layer shadows /etc/resolv.conf and other files from the filesystem but this can cause problems if we're bootstrapping the system. Signed-off-by: Petros Angelatos <petrosagg@gmail.com>

There was a problem hiding this comment.
The second flag.StringVar will override the first one. I am not sure I get this. https://play.golang.org/p/7Pr_o3He8V

This PR introduces another type of containers, namely bootable containers, that are meant to be used to bootstrap a system. The distinction is achieved by specifying the
bareruntime instead of the defaultrunc. This disables some actions performed by Docker that interfere with the boot process.This PR also adds a new command, mobynit, which is meant to be statically compiled and run as PID 1 of a system running bootable containers. This commands contains the absolute minimal code to assemble the root partition of a bootable container, pivot root, and start the normal init process.
The sysroot is mounted at
/mnt/sysrootof the container mount namespace to allow the bootable container to update itself.
