Proposal for Hosting Community Spin Binaries
1. The Fedora Project will make a spin compose host available to select members of the Spins SIG, hereby known as composemasters. 2. The Spin SIG composemasters will use the Fedora Infrastructure managed compose host to generate binary images, source images and signed checksums. 3. The signed checksums will be archived into the cvs space associated with the spin being composed. 4. The generated binary images will be moved to community hosting and will be purged from the compose host. 5. The spins.fedoraproject.org webspace will be updated to list links to the community hosting 6. the spins.fedoraproject.org webspace will also include information on how to verify the signature on the checksums, and verify the checksums match the images.
