Comment:

 back to this topic: Here on our system I found > 1.7TB of NULL files in a
 single location, all
 uncompressed.

 What about having a "null2" file which is compressed and with index. If
 present, fine, otherwise use the uncompressed well known null file format?

 For backward compatibility, r.null could extended to convert from
 compressed null2 to
 uncompressed null (similar to v.build for the new spatial index in G7).
