As I see it there are 3 ways to do it:
-Make it a compile time option that only configures it for a single
system with any devices that are added to the RAID.
-Make it a runtime option that can change based on how the
administrator configures it.
-A non-user facing option that is configurable by someone like a
distribution maintainer for all systems using the Binary Distribution.

As I see it, DS would like something like the third option, but CAM
(ostensibly a SysAdmin) wants the second option.

On the other hand, I implemented the first option. 

The first and third option can co-exit, the second is an orthogonal
target that needs to be setup separately.

Or we can make all options co-exist, but make it more complicated.

Please let me know which implementation is preferable, and, if you just
want me to expand the description (as DS' mail asked for) or redo the
entire setup.

Thanks
