       systemd-veritysetup@.service, systemd-veritysetup - Disk verity
       protection logic

SYNOPSIS
       systemd-veritysetup@.service

       /lib/systemd/systemd-veritysetup

DESCRIPTION
       systemd-veritysetup@.service is a service responsible for setting up
       verity protection block devices. It should be instantiated for each
       device that requires verity protection.

       At early boot and when the system manager configuration is reloaded
       kernel command line configuration for verity protected block devices is
       translated into systemd-veritysetup@.service units by systemd-
       veritysetup-generator(8).

       systemd-veritysetup@.service calls systemd-veritysetup.

COMMANDS
       The following commands are understood by systemd-veritysetup:

       attach volume datadevice hashdevice roothash [option...]
           Create a block device volume using datadevice and hashdevice as the
           backing devices.  roothash forms the root of the tree of hashes
           stored on hashdevice. See Kernel dm-verity[1] documentation for
           details.
