Subject: [PATCH] 90mdraid: adjust stock mdadm udev rules

Currently shipped mdadm rules incrementally assemble all imsm and native

raids, and do so unconditionally. This causes few issues:

- fine-grained controls in 65-md* are shadowed - for example,

  mdadm.conf's presence tests or uuid checks

- 90dmraid might also conflict with 90mdraid, if user prefers the former

  to handle containers

- possibly other subtle issues

This patch adjusts the behaviour.
