CoreOS is already working great on GCE http://coreos.com/docs/running-coreos/cloud-providers/google...
We also wanted to offer a way for regular Debian users to get easily started with Docker on GCE.
The agent https://github.com/GoogleCloudPlatform/container-agent and manifest format https://developers.google.com/compute/docs/containers#contai... are not distro specific, and the glue to start them on boot could be easily adapted to other distro.
As the Fedora docs say, it's "often running in uncharted innovative territory," which is great if you want the latest stuff on your desktop, but it's not what you really want in a server distro. Red Hat Enterprise Linux (RHEL) is derived from Fedora every few years so it's battle tested and stable, in the same way Debian is.
For servers in the Red Hat lineage, use RHEL or CentOS, esp now that Red Hat has officially joined forces with CentOS (http://www.redhat.com/about/news/press-archive/2014/1/red-ha...).
And we have to use the indefinite article, "a desktop", never … your desktop.
