OK, I know understand your requirements and indeed something like kpartx
is required if you want to be independent from LVM or the filesystem.

I’m not sure what adding it in the ISO would require (outside having it
in the repo of course), but anyway you can still add it yourself it if
you have an internet access during installation. ;)

Feel free to enhance the wiki with this example, being quite different
from the LVM one it might interest others, and eventually lead to the
inclusion of kpartx in the repos (and latter maybe even in the ISO,
though again I’m not sure about the criterion here).
