When booting using my dm-crypted root partition, dm-crypt asks me for passphrase entry twice (once for verification): A passphrase is required to access volume sda1. I don’t want to enter my passphrase twice.
I realize that if I enter my passphrase wrong, dm-crypt has no way of knowing this, and will try to decrypt with the provided key anyway.
Is there an option to turn it off? Is there a reason why it should definitely not be removed? Would it ruin something if I tried to patch this out and recompiled my own dm-crypt?
