Ofcourse, because you're searching for qemu-SYSTEM-s390x.  But you're
using /usr/bin/qemu-s390x-static (that's the one which qemu-debootstrap
installs into chroot), and you install qemu-USER-static which provides
that file.

Heh.  I read this like "for any bug I encounter in my life, I've been
told to bug qemu-user" :)  No, please don't, use common sense please :)

OK, will do :)

Forgive my ignorance...

Which Debian list should I go to for troubleshooting it further. I'm
going to need a little assistance in getting things tweaked properly,
and I don't think a bug report is the best place for it.

I'm kinda envious you have a working S/390 environment and I don't.
And I need to do some platform specific testing.
