You cannot replicate the full filesystem among multiple hosts with their own drives though, can you?

With OSTree my team can deploy a commit over an existing ones to a field of 60k embedded Linux devices. Similarly bootc is a great alternative for deploying images for dedicated or virtualized servers.

yeah you can? what you on about
How do you tag / mark a commit a snapahot of all files in an OS image that's independent from each device's local state and then move them from one commit to another atomically? Basically a `git pull` on a branch but binary and atomic.

CoW is strictly local. You can make a snapshot of local state sure and even atomically change it. But that's not we want.

if i know all devices are on the same root? you just ship the snapshot diff and if it does not sync to the fs you just resync it all
