A few details on the "standard linux support" part.

To remove the hard dependency on the AUFS patches, we moved it to an optional storage driver, and shipped a second driver which uses thin LVM snapshots (via libdevmapper) for copy-on-write. The big advantage of devicemapper/lvm, of course, is that it's part of the mainline kernel.

If your system supports AUFS, Docker will continue to use the AUFS driver. Otherwise it will pick lvm. Either way, the image format is preserved and all images on the docker index (http://index.docker.io) or any instance of the open-source registry will continue to work on all drivers.

It's pretty easy to develop new drivers, and there is a btrfs one on the way: https://github.com/shykes/docker/pull/65

If you want to hack your own driver, there are basically 4 methods you need to implement: Create, Get, Remove and Cleanup. Take a look at the graphdriver/ package: https://github.com/dotcloud/docker/tree/master/graphdriver

As usual don't hesitate to come ask questions on IRC! #docker/freenode for users, #docker-dev/freenode for aspiring contributors.

does this mean that docker will run on 32 bit systems ?

I see docker come around every now and then here. I'm a smalltime developer shop, small team, small webspps. What can docker do for me?

Can this reduce the time it takes me to put up and Ubuntu installation on Digital Ocean?

Is this more for larger companies ?
