Comment 4 for bug 1869075

Hrm, do we know if this LVM over multipath worked before?

In my recreation, I'm not seeing how this will work without curtin changes. We currently do not write out an lvm.conf which restricts scans to multipath devices only. I've got local changes to reproduce a failure similar to this, and I can successfully install, but the boot afterward fails due to root=/dev/mapper/ubuntu-vg-ubuntu-lv ... initramfs attempts to bring the vg/lv online and at this point, it complains again of the duplicate paths...

I suspect this has never worked before, but I'd like confirmation.

Curtin will need to emit a lvm.conf with a filter for multipath only devices.
