yep .. dead in the water.
This just gets worse.
So I netboot the thing and mount the filesystems and then use gzip
to compress the file to vmlinuz and that fails :

So what unspeakable horror show does this want ?
Old school compress ?
Well I netboot the thing and then reset the symlinks back to
the old kernel stuff. Reboot and try this :
root@nix:/boot#
root@nix:/boot# file vmlinuz-3.2.0-4-sparc64
vmlinuz-3.2.0-4-sparc64: gzip compressed data, from Unix, max compression
root@nix:/boot# file vmlinuz-6.12.3-sparc64-smp
vmlinuz-6.12.3-sparc64-smp: gzip compressed data, was
"vmlinux-6.12.3-sparc64-smp", from Unix, last modified: Thu Aug 28
08:07:31 2025, max compression
root@nix:/boot#
root@nix:/boot# unlink vmlinuz
root@nix:/boot# unlink initrd.img
root@nix:/boot# ln -s ./initrd.img-6.12.3-sparc64-smp ./initrd.img
root@nix:/boot# ln -s ./vmlinuz-6.12.3-sparc64-smp ./vmlinuz
root@nix:/boot#
So there we see that the file is gzip compressed.
root@nix:/boot# cat silo.conf
root=/dev/sda4
partition=1
default=Linux
read-only
timeout=100
image=/vmlinuz
label=Linux
initrd=/initrd.img
image=/vmlinuz.old
label=LinuxOLD
initrd=/initrd.img.old
root@nix:/boot#
shutdown smooth and watch it fail ...
