I wonder what it would take to get qemu to emulate an atari st well
enough for this kernel to boot on it? (I played with aranym back in the
dawn of time, but the I/O devices were kind of painful to use.)

Toybox is working fine on j-core, which is a nommu platform. The
http://github.com/j-core/mkroot project is a tiny system builder that
builds with a supplied cross compiler, just:

  CROSS_COMPILE=cortexm- ./mkroot.sh

Output is an initramfs directory (and cpio image made from that
directory). It requires my patch to apply DEVTMPFS_MOUNT to initramfs,
which I need to resubmit upstream... (Remind me to send you an updated
version of that tonight.)

Alas, toybox's shell still isn't finished so that build script uses a
selecton of busybox commands (mainly hush) to fill in the gaps. I'm
working on replacing those, but it won't be ready for this next release.
(Past month and change has been an attack of life...)

May I forward this reply to the toybox mailing list?

Thanks,
