It’s now possible to start up a vkernel(7) using a COW disk, meaning copy-on-write. One image can be used and reused for multiple vkernels without changing, and all disk activity goes to memory instead.
A running description of activity related to DragonFly BSD.
Pretty interesting. How are things shaping up with regard to Hammer2?
Cool. COW kernels on a beefier filesystem than UFS. Udderly delightful. I so require coffee right now…
