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 :

ok boot /pci@1f,0/ide@d/disk@0,0:a
Boot device: /pci@1f,0/ide@d/disk@0,0:a  File and args:
SILO Version 1.4.14
boot:
Allocated 64 Megs of memory at 0x40000000 for kernel
Uncompressing image...
|
Decompression error: invalid compressed format (err=2)

Error loading /vmlinuz

Image not found.... try again
boot:

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 ...

This is now a waste of my time.
