That depends on what people want them for. The latest patches are found 


If you want patches against sid packages, I did upload some, but they are 
obsolete now. More backporting is required. (I guess that's what happens 
if you don't wait for the upstream release.)

If there was a working URL, people might expect "etch-m68k" to work like 

The debian project kicked out the m68k architecture from the release 
process before Debian 4 "etch" was officially released. So "etch-m68k" is 
not really etch, and is not actually supported.

The last official debian m68k distro was Debian 3.1 "sarge". Though an 
official release, it is about 5 years obsolete, and not much good for the 
kind of development work that you alluded to.

The "rd" in "initrd" means ramdisk. You may not need one if you have the 
necessary modules built into your kernel.

The ISO that I used is the "netinst" ISO, which installs packages from the 

The download is called debian-etch-m68k-m68k-netinst.iso and is found at
I downloaded mine in October 2008. You might want to try a newer one, or I 
can send mine (it has minor issues).

If your quadra has a CDROM drive, burn the ISO to a CD-R (not RW), slowly. 
If it doesn't, there are other ways.

These ISOs require that you boot with kernel arguments
"suite=etch-m68k modules=etch-support"
If you use the kernel and initrd from the ISO, this should be sufficient. 

When I did this, I used my own kernel build instead of the kernel and 
initrd on the CD. If I recall correctly, I added "root=/dev/sr0" to the 
kernel command line. (Sorry I can't confirm this right now.)

The kernel will panic if there's no root filesystem. I guess you don't 
have an initrd or root filesystem yet, so this is to be expected.

I wasn't asking about m68k but debian of any kind. (Even a text mode 
Ubuntu install would give you an idea of the process.)

"etch-m68k" was never an official release, as I mentioned, so the 
installation guide might not be everything you'd expect.
