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

SYNOPSIS
       systemd-veritysetup@.service

       /usr/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.

           Added in version 250.

       detach volume
           Detach (destroy) the block device volume.

           Added in version 250.
