Well, two things.  First, when I try that I get a similar error from yaboot.
That is, I netbooted yaboot and its .conf includes:

image=enet:,/fc/devel/ppc64/vmlinuz
        label=rawhide-ppc-ppc64
        initrd=/fc/devel/ppc64/ramdisk.image.gz
        read-only

Those files are copied from development/ppc/os/ppc/ppc64/

method 'load' failed 000000300

etc.

Second, what I would like to be doing is testing the rawhide images.
So avoiding them because they don't work defeats part of the purpose.

OTOH, today's boot.iso gives me a python error in anaconda startup, so I
don't feel like I'm desperately missing out not having a smooth netboot
experience just now. ;-)

Maybe there are some guaranteed-useless drivers enabled you can prune?

I tried this and it helped in the sense that I don't get the ELF loading
error message any more.  Instead, it slurps the file happily, then blinks
and restarts yaboot stage 1.  So, not that much help.

I in no way trust the image I made.  I used rawhide images, stubs, and
script to start with, but the rest of the tools are cobbled together on an
old install and maybe not good enough.  If you would like to mkzimage one
for me with tools you trust, I would be glad to test it.

Oh, and maybe I don't have to bother filing a ppc64-utils bug and you can
just get this shoehorned in for the next schlub that thinks he can figure
out how to use that script on uninstalled input files.
