Hi,

Is there a place where the difference between these latest kernel binary
images is documented, other than looking thru the config files or the
descriptions of the packages.

When I install Etch on my machine from the daily built, it pulls in -486.

With that and grub I can boot into a USB disk.

But when I install linux-image-2.6-k7 (my processor) the boot will fail,
because he cannot find the root device, meaning the initrd failed
somehow.

So it would seem to lie in the difference between the kernel images, but
what is their difference?

I don't think the difference is necessarily the kernel image, but
rather the state of the system when the initrd is generated. The
initrd generated during install is in a different environment than
that which is generated once the system is up and running. I would
look into the parameters used to build that initrd and see if you can
grok the differences. It may be, for example (I'm making this up as an
exercise), that the install builds the initrd using a "dependent modules"
model where the running system uses a "most modules" model. I think
the difference being that the dependent model looks at what is
actually needed where the other just grab most of them. If one of the
required modules is *not* in the group of "most" then there is a
problem. Also -- maybe the kernels are naming the devices differently?
that could cause a not-found / partition.

just some thoughts to hopefully help you on the way.
