> I'm hoping to use dm-verity in the raid subsystem soon. Given that the purpose of dm-verity is simply to confirm that was is later read from disk, is exactly what was written to disk earlier, it doesn't need a secret.
Isn't that exactly what dm-integrity can already do today? What would using dm-verity instead buy you, if you can't keep the private key secret because (presumably) you want to write to your array?
