This may appear to be slightly off topic, please stay with me...
I am trying to compose an f8 ppc iso on an x86_64 machine. This
should work, as there is no native ppc code run, right?. All goes
well until we get to the mkisofs stage.
There appears to be 2 bugs involved, see [1].
As part of the debug, I finally got mkisofs to enable the use of the
-magic flag, which finally gets me back to the anaconda part.
In anaconda, one sees that scripts/mk-images.ppc is the call site, is
attempting to use "/usr/lib/anaconda-runtime/boot/magic", which indeed
does not exist.
Looking at the anaconda source, I did find a magic file, in
bootdisk/ppc/magic. This file is not in the installed
/usr/lib/anaconda-runtime anywhere.
Would this be the correct file?
Should bootdisk/ppc/magic always be installed? Or for that matter,
the entire contents of bootdisk/*?

Wrong. buildinstall has to be ran on ppc, in order to figure out the
kernel stuff right and various other things.

That has me confused, What does buildinstall do that requires the
target's CPU?

It creates kernel boot images and susses out what libraries should be
included and what modules should be included. For now these need to be
ran on the arch it is composing.

That's what you said last time. I still don't comprehend.

*shrug* Perhaps one of the anaconda developers can chime in with more
details, but it is what it is. If you don't run it on the arch, you
don't get all the right modules in the initrd and various other
problems.

upd-instroot runs yum on the target architecture to set up the root tree that we pull files from to build the stage1 and stage2 images.
Also, we exec the dynamic linker to collect shared libraries we depend on since that stuff tends to change from time to time as things grow and shrink their dependencies. See get_dso_deps() in buildinstall.functions.

Yum is pretty easy to fake out as far as what arch you're on.

This is the one that is likely causing the need to be on the target
arch.
