You could do something similar to the process we use to make pre-built 
images. For example, your linaro-media-create line currently is probably 
like:

   linaro-media-create --dev overo --mmc /dev/sdb .......

You can change this to something like:

   linaro-media-create --dev overo --image_file file.img --image_size 3G

This will create file.img which you could then "dd" to your SD cards.
