Using a very large ipk feed does indeed work nicely to generate images.
However, generating Packages can take ages ( and so do image rebuilds
because of this ). That's about the only problem I see w/ One Giant Feed

I wasn't exactly running into real ipkg bugs. I had problems with
packages using machine-specific stuff for some models ( say all
sl-c3x00) and hence having their ARCH set as $MACHINE, but not for other
models ( like collie, poodle ) having their ARCH set as $ARCH. 

It's a packaging bug, not an ipkg bug but annoying in any case ;)

Exactly.
