Rebuilding a Raid 1

[Bad Bod]

Hi Heinz,
  Seeing as all the major distro's use this for detecting RAID during
install from live CD, and right now they all fail, then you might suggest
to them that this project is dead and you no longer support. Quite why they
started using this for RAID, I am not sure. It did work, then got broken.
Maybe they still think it works? It does not.

Please ask the major distro's to start using mdadm instead of this broken
thing they are still using.


Regards
David
