We have a custom coreos build (specific portage overlay) which we use to build our images.
Right now we just build the image and call image_to_vm to create the cloud volume snapshot binary blob. I would like to be able to move to something that is compatible with the coreos partition swapping but am having trouble finding a way to either: 1. Have a non-official update channel local to our organization 2. Have a way to really-really-manually update a coreos node. Looking at https://coreos.com/os/docs/latest/manual-rollbacks.html it seems it might be possible to simply update the not-in-use USR-? partition from the "new" image and continue from there. Is there a way to either use a non-official update channel, or to manually push an update into the unused USR partition? Thank you, Charles Allen
