Hi igor,

Thank you very much for the documentation.

As of now i'm only trying to Authenticate rootfile sytem using dm-verity and i don't want to Encrypt it.

Mostly dm-verity is used in Android devices, As it is kernel’s device mapper module i believe it should support for linux device too.

I didn't find a document implementing dm-verity to verify linux rootfile system. If you have a procedure please share with me.

Regards

Khaleel

have you implemented the dm-verity on linux ,rather than Android?

I face the same task as you.

Is there any documents to refer to?
