Comment 21 for bug 1869075

The 'path' key in the disks results in curtin resolving the path to the disk differently; since sdb does have a holder (multipath layer) we attempt to clear and wipe the partitions, however since they are path members, we cannot write to them directly.

Now that I can recreate I can start working on a fix for this. I think I'll need to convert more of our vmtests to using the path key (which is unstable for us in VMs but in practice for subiquity it is stable). Something to discuss on emitted config here I think.
