create official unshare variant for ARM

[Govinda-Fichtner]

While trying to get Docker integration tests running on ARM one major problem is that the current unshare image only works for x86.

Together with @StefanScherer I created a quick'n'dirty variant of the unshare image which can be found here: https://github.com/hypriot/armhf-unshare

As the unshare image is used for the integration tests makes me think that it also should be part of the official docker-library. Same as for the busybox image.

How could we best achieve this? How could I help?

I would say checking out the process in github.com/docker-library/official-images

@jfrazelle Just to make it clear: you agree that the images used in the integrations tests should be part of the docker-library/official-images?

[jessfraz]

eventually yes, but for now we can use personal repos

I'm still hazy on what makes the unshare image different from the unshare binary included in the Debian base image itself?

[jessfraz]

@jfrazelle @tianon The problem is/was that some versions of unshare don't work appropriately on all kernels. The jess/unshare image is of a version that is "mostly compatible" across different kernels. Also, it's really small.

If the version of unshare in the latest debian image works well across kernels, then by all means, use it instead.
