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.
