I tried this in QEMU. Launching /sbin/init fails and the kernel panics
with "Attempted to kill init".
When I examined the initrd-serconsole.gz file, I see that /dev is empty.
So I used "root=/dev/ram init=/bin/sh" and I got a prompt:
bash# mount -n -t devtmpfs none /dev
bash# exec /sbin/init
Remounting root file system read-write

I didn't dig any deeper. That initrd is 20 years old, and may or may not
work with 20 year old kernels. Who knows?

The kernel seems to be fine. It works with a busybox initrd I have.

If you want to install Debian, you should first try the kernel and initrd
from the Debian installer ISO. You can find it here,
