Yeah it seems to have crept up a bit. The image went from this Cloud
SIG over to the Base WG (since there's so much interest in Docker), but
I think we still have a vested interest in keeping it small. In
general, much of the regular dependency-shrinking work we've been doing
should help here.

Unfortunately, the easy work is mostly done, as is some of the
moderately hard. The next most helpful thing is probably making a
compact version of python sufficient for yum, cloud-init, grubby (new
version), and _possibly_ firewalld. As it is, it's about a third 

Oh hmmm. I see that grub2 got into the docker image somehow. That
should probaby be fixed, and provides a big savings even in the
compressed version because that's the only thing that pulls in
fedora-logos.

Hmmm. Firewalld too. That really doesn't need to be there, does it?


That said, the docker image we're producing *is* only 90MB compressed —
see
<https://dl.fedoraproject.org/pub/fedora/linux/releases/21/Docker/x86_64/>
— and 241MB uncompressed. Something _additionally_ weird is going on.



Are you interested in taking point on this for Fedora 22? Or finding a
handful of people who are interested in working with the Base WG to
figure it out?
