Depending on if you are using OE-Core or classic OE say you are using OE-Core
then you can use core-image-minimal target that will generate minimal packages
into image thats required to boot.

in classical OE there was base-image, micro-image that you could use
I dont think there is exact image you want but then its not that hard
to create one

fetch operation should happen first time thereafter it should always
look in your
DL_DIR before it goes out and fetches stuff
