Hello,
I would like to submit a Cinnamon spin for review and possible inclusion in future Fedora releases, though I am sure it is too late to include in F22. It is a spin simply using the Cinnamon desktop environment group, and I have been working with the Cinnamon maintainers to fix any issues that have come up in F21 or F22 beta. The proposed spin page is here:
The kickstart files are available in this repository:
I have uploaded ISOs for both F21 and F22 beta here:
