reassign 330445 linux-kernel-di-powerpc-2.6
thanks
Please read on below for an explanation why this is not a
kernel-package issue. The solutions being proposed now call for a
grand plan betweeen all known boot loaders, and boot loader
configuration, and automated discovery of boot loader
configurations -- and until something like that is in place, it is
not buggy for kernel package generated images to fail to install
unless a human has indicated it is ok (otherwise the system may be
rendered unbootable).
So, this is a kernel-package feature, not a bug :P

The installer does not know better then the user whether or
not initrd's are supported in the boot loader -- and definitely not
in the general, real world case. And the idea is to cater to as many
user as we can, not just the case of ourselves (I, for example, never
ever use initrd's on my production boxes).
If you think the initrd question is useless, I don't think you
have thought through real world scenarios and use cases.

Since I do not have a powerpc machine, it is hard for me to
tell what the problems are. Some of them, if memory serves me right,
are from an attempt to ship a generic, unusable kernel image in
powerpc, and on the fly create an usable vmlinuz -- which is an
unusual situation, and most of that has not been designed by me. I
would be happy to have a look at a solution for powerpc instead of
delegating that to the architecture people.

I have no idea what you are talking about here. Can you
elaborate?

I maintain you still do not know what you are talking about
here. How can the boot loader maintainers and kernel team maintainers
know about, say, my machines, which usually have both grub and lilo
installed? How would you know if I have initrd turned on or not?

Having a profound conviction is nice. Have a technical
solution is better.

What part of "Debconf is not a registry" is so hard to
understand?

Maturation? Faugh. Say, user A installed lilo. During
installation, had initrd turned on, perhaps even using debconf.They
then installed grub, again with initrd turnd on. ASfter a bit, they
overwrote the boot loader in /dev/hda3 (which is /booot, and toggled
bootable using fdisk). Then, they started using their own kernel,
and turned off initrd's in /boot/grub/menu.lst.
How can you discover this reliably, using just debconf?

So, in todays set up, this is not a bug in kernel-package, so
I am reassigning this back to where it came from.

Err , sure -- depending on boot loaderes know about this? And
which boot loader scrip in the example above should I trust? Frank;y,
this is not a workable idea right now.

Indeed. Come up with a solution that works for the scenario I
have given above, and we may be getting somewhere.

Good. When such a plan, and a workable one, is in place, feel
free to open a wishlist bug against kernel-package. At this point,
however, it is the debian installer that is buggy.

I have always answered emails sent to me. I would also prefer
to start working with the problem statement, not with a proposed fait
accompli, since there are times, like now, where I consider the
proposed solution as being suboptimal when it comes to kernel
packaging --- but I have been doing this for ten years.
