This is a good point, but:
The current LVM2 behaviour is confusing for users that upgrade from 
2.4/lvm1 to 2.6/lvm2 so i would like to address it.
LVM2 already code already contains exceptions for MD devices.
since we have a configuration file we could add a configuration switch 
for ignoring devices with md superblocks (possibly defaulting to ignore, 
which is what users expect)


WDYT?
