It looks like this is defined (as DEV_PREFIX and RDEV_PREFIX) in 
config/config.h based on the results of ./configure.  You could add the 
check to the configure script or just change the values of (R)DEV_PREFIX 
in config.h.  I'm not sure if this will break anything, so test it.

Well, IMO, mount points look a lit nicer than device names.  They also 
stay consistent should the underlying hardware/config change.  Just my 
$0.02.
