Regarding the ELDK target filesytem, all I did was try to strip it
down using 'ppc_4xx-rpm -e package' as far as I could go. The
remaining packages below are there because the above command would
could not remove them because of package dependencies. So, the reason

Such an approach makes little sense for building an embedded system.

Thanks for the feedback Wolfgang. My intention ultimately is to build my tgt filesytem from the ground up. The ELDK tinkering was an attempt to provide a comparison platform to try and help me understand why my bare bones filesytem wasn't working...

Why do you care about packages and package dependencies? You will not
use a package manager in hte target system, so you are free  to  copy
or remove individual files as you like.

Also, the approach to strip  down  a  general  purppose  distribution
(even  an embedded one) does not make much sense - as I wrote before,
you better design your system bottom up by  starting  with  an  empty
filesystem  and  just  adding  the  really required components. Where
"required" means "required to perform some task you defined  in  your
project specification".

That's what I'm trying to do, building from the ground up that is. Just can't get my bare bones system (basic rootfs dir infrastructure with busybox) to boot yet :-(
