Originally, mdadm used /var/run/mdadm/mdadm.map file to store the temporary
mappings of incrementally added devices to device names. Unfortunately,
this breaks incremental assembly if used early in the booting process.
Specifically, root may still be read only. Since incremental assembly is
largely a udev specific feature, and udev needs a writable /dev tmpfs mount
even when root is still read only, it's safer to put our mdadm.map file in
/dev/md so that we can write to the map file no matter how early in the
boot process we are attempting to use incremental assembly.
since we are at it, what about using a #define for the file path?
