that should work, I remember doing just that.

Ah, the 'hidden' pieces.
.treeinfo should be there. I'm not exactly sure, for what it is used,
but with its contents, it did sound like a good idea to have it. Check
your Distro-Iso, or the repos, there are .treeinfo files there.
Just copy it to your DISTRO-IMG-DIR (specified in the "Distro" section
of spacewalk).

updates.img and product.img are not around per default.
Unless you need it, for e.g. patching anaconda on the install distro,
then, e.g. an updates.img could be created, that just contains the
patched files and some magic, to seemlessly fit into the kickstart image.

My guess is, that 'product.img' can do something similar, and if
available gets pulled into the early/pre-anaconda setup-steps.
