💖 SYSTEMD-CLONESETUP 💖

okay bestie, so you know how we're always out here cloning disks like it's nothing? yeah. this is that. we're talking systemd-clonesetup and its lil service buddy systemd-clonesetup@.service — together they set up and tear down dm-clone devices. it's giving disk-clone main character energy, fr fr. 🦋

✨ NAME ✨

systemd-clonesetup, systemd-clonesetup@.service — besties who set up and tear down dm-clone devices. no cap. 💅

🌸 SYNOPSIS 🌸

systemd-clonesetup add NAME SOURCE-DEVICE DEST-DEVICE META-DEVICE
                   [OPTIONS]

systemd-clonesetup@.service

like. that's it. that's the whole vibe check. 😌

🎀 DESCRIPTION 🎀

so systemd-clonesetup is literally the tool that does the two things you need a clone device to do:

• add — sets up (✨ creates ✨) a dm-clone device
• remove — tears it down (💀 bye bestie)

and the way you'll mostly meet it is through systemd-clonesetup@.service units — those don't just appear out of nowhere, they get generated from /etc/clonetab by systemd-clonesetup-generator(8). it's a whole pipeline and honestly? iconic. 👑

okay now the positional arguments — NAME, SOURCE-DEVICE, DEST-DEVICE, META-DEVICE and OPTIONS — these mean exactly the same thing as the fields of the same names in clonetab(5). same energy, same meaning, no surprises. 🤝

and about OPTIONS: right now the only supported option is region-size=BYTES, where BYTES is measured in bytes. and yes queen, standard suffixes like "K", "M" and "G" are supported, so you can absolutely write region-size=4M and be fine. 🍓

ngl, don't go inventing options in there — region-size=BYTES is the whole menu rn. 🙈
