NAME

       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.

       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.
