I think that all the arguments for using DM are techinical arguments not
emotional ones. oh well.. you're free to write your code I'm free to not
use it in my kernels ;)

Ok, the technical arguments I've heard in favor of the DM approach is 
that it reduces kernel bloat.  That fair, and I certainly agree with not
putting the kitchen sink into the kernel.  Our position on EMD is that
it's a special case because you want to reduce the number of failure
modes, and that it doesn't contribute in a significant way to the kernel
size. 

There are serveral dozen such formats as DDF, should those be put in too?
And then the next step is built in multipathing or stacking or .. or .... 
And pretty soon you're back at the EVMS 1.0 situation. I see the general 
kernel direction be to move such autodetection to early userland (there's 
a reason DM and not EVMS1.0 is in the kernel, afaics even the EVMS guys now 
agree that this was the right move); EMD is a step in the opposite direction.
