Supporting two entirely separate code paths for a single device is *bad*.
Because we will need both code paths anyways as for some bios-raid's mdraid will be the preferred method, while others will only be supported by dmraid. Given that we need the 2 code paths anyways, making which one to use configurable when both support the type of bios-raid is much easier, and certainly much less error prone, then trying to handle device name changes when upgrading.
