I'm pretty sure that this is the correct procedure for creating a
renamed spin:
Download the generic-logos and generic-release or fedora-logos and
fedora-release .src.rpms. Rename them and change them to your liking.
Rebuild them. (Whether you start with generic- or fedora- depends on if
you intend to abide by the Fedora trademark restrictions.)
Create a new yum repo for your spin. Put the new dowdlelinux-logos and
dowdlelinux-release src.rpm and noarch.rpm files in the repo.
Add the repo in the spin kickstart files so that you're loading packages
both from Fedora and from your repo. Also add:
-generic-release
-generic-logos
-fedora-release
-fedora-logos
+dowdlelinux-release
+dowdlelinux-logos
Then build your spin and it should just work without any ugly stuff in
the %post section. Also, this will give you the opportunity to change
the Plymouth theme, desktop program menu button and so on.
