+Subject: [PATCH] stages/dmverity: make device objects more generic
+
+We need to pass loopback devices for these properties, but the schema
+says that there will be a `path` property, so osbuild complains.
+
+osbuild is right of course, but this definitely *did* work in an earlier
+version, so something changed. Ideally, we'd narrow down here what
+happened exactly, but at the same time this approach of just making the
+property more generic matches what's done in e.g. the `zipl.inst` stage
+where we also use a loopback device.
+
+For reference, this is where we use this stage:
