I don't disagree with you, I just don't think we're there yet, and I'd rather
lean towards incremental progress. Right now there are some examples in the
package's documentation, but it doesn't seem to be kept updated, and there's a
way to dump this from a running system. The longer term goal isn't to make
device-mapper-multipath create a template for us, but to make it create the
initial dm tables in the first place.
I'm actually not that far off from that point - we're just not there yet.
