ugrd missing dm-integrity support

[gentoo-based]

It seems that cryptsetup when using --integrity mounts a /dev/mapper/cryptroot_dif before actually mounting the real cryptroot to check for the checksum.

how did you set it up? I haven't worked with the integrity option before

To setup an integrity-based encrypted root, you have to add one option to cryptsetup while encrypting your disk which is --integrity and the hashing algorithm you will use such as hmac-sha256 so the full command is

cryptsetup --integrity hmac-sha256 --type luks2 luksFormat /dev/sda2

#350

if you try the dev branch it may work now (tested in a vm)
