# Description

`systemd-clonesetup` is used to set up (with `add`) and tear down (with `remove`) dm-clone devices. It is primarily used via `systemd-clonesetup@.service` units generated from `/etc/clonetab` by `systemd-clonesetup-generator(8)`.

The positional arguments `NAME`, `SOURCE-DEVICE`, `DEST-DEVICE`, `META-DEVICE`, and `OPTIONS` have the same meaning as the fields in `clonetab(5)`.

Currently, the supported option in `OPTIONS` is `region-size=`\<BYTES\>, where \<BYTES\> is measured in bytes (standard suffixes like `K`, `M`, `G` are supported).
