You cannot forbid users to chose arbitrary filesystem layout during

rollback (or even create snapshots actually). If snapper allows it, how

Because snapper makes a filesystem snapshot and rollback, not a system
What is the difference? snapper does not care at all if this is your
home partition, data partition or root filesystem. This doesn't make
any difference for snapper. And since snapper does not know what you
snapshot and if rollback can work, it cannot warn you.

That's why snapper/rollback of the root filesystem is only supported
with the default filesystem layout (including /@) and nothing else.
But this does not mean, that you cannot create a complete different
layout which works, too. As we e.g. did for openSUSE Kubic.
