Using the above process filled up my disk. For some reason the pagemap
file grew to 77 Gigs and on that partition it ran out of space. 

-r-------- 1 root root  77G Mar  8 16:37 pagemap

I'll try on another (slightly larger) partition. How much disk space
should one have for this? 77 Gigs seems like an awful lot of space for
an image. All the source code for a image and yocto tooling in
comparison comes to about 60 Gigs or so.

Regards,

Jeremiah
