This PR fixes the "operation not permitted" error encountered when pulling certain images on AUFS with ext4.

Fixes moby/moby#6874

While waiting for an official release including this fix, is there a way to apply these flags to an already-built boot2docker VM image? Or given that these are kernel configs, do they need to be part of the OS install and aren't just a simple fix on a running VM?

Unfortunately, they have to be compiled into the kernel, but boot2docker is
built using a Dockerfile, so if you've got a working install of Docker you
should be able to build it and use the resulting ISO!

I have a running VM of the latest release of boot2docker; let's see if we can Inception-ally create boot2docker within boot2docker...

EDIT: Result: nope....

docker@boot2docker:~/boot2docker$ docker build -t boot2docker . && docker run --rm boot2docker > boot2docker.iso
[...]
Step 37 : RUN echo root > $ROOTFS/etc/sysconfig/superuser

Ah well, I'll wait for the official release to update.

Can confirm that deleting the VM in VirtualBox, building the boot2docker.iso from master and copying to ~/.boot2docker fixes the "operation not permitted" error.

For me the issue was with pulling jboss/wildfly
