- switch to mdadm (instead of raidtools)
- create mdadm.conf instead of raidtab - internal {raids} is no more indexed by X for mdX, and so don't have holes anymore - internal {chunk-size} is now a number in KiB - internal {raid} is the raid device name, not the number - various cleanup for raid detection
