  I recall doing some poking around to something simular to this, and
the best I recall is SUPPORT_RECONSTRUCTION being built into the
kernel.  This was SEVERAL years ago, I have no idea what the current
state of this kernel capability is.

  Basically, what this allows is for given drives to be defined, and
allows the system to automatically reconstruct the array.  The purpose
for this is to allow for spare drive situations, where the spare drive
would be used to recreate the RAID array after failure, but I suppose
could also be configured in such of a way to automatically reconstruct
the array onto an existing disk, but it's a guess.
