I had a quick discussion about this and one suggestion was to add dm-verity kernel module parameter instead of a new config option. The idea is that if you can control kernel boot commandline, you can add it there with the same effect (expecting that root device is on dm-verity as well). Isn't this better option or it is not going to work for you? Milan
