Isn't it quite big for a "Nano" image? It looks like a size for a
'developer' version.
Do we know why it's so big? 
In comparison, ARM developed AEL/ALIP
( and we were
hoping to use Linaro's Nano image from now on. 
The size of the AEL/ALIP minimal version (busybox, ssh) was only 25MB
(compressed - Cramfs). And the version with X11 and a desktop was 55MB.
Those images are useful for development boards with 64MB of flash or when
using CPU models.

This looks good if it's an easy change.

Does it address the problem with Modules and firmware?
Is it possible to get an image without Hwpacks?
