Good question. But the problem is how to do that?
Certainly the new kernel you are installing does not *require* the
'discover' package to be installed. So the kernel package can't list
it as a Depends: because people not wanting discover would rightfully
call that a bug. So how would this get installed automatically on an
I suppose this could be documented more visibly in the upgrade release
notes for the new kernel. I looked through the above guide and find
that discover and hotplug are mentioned in the sound configuration
only. I would prefer if this were documented as recommended in the
kernel upgrade section. I just filed Bug#324401 with this addition
suggestion for the release notes.
Users upgrading from a non-modular bootstrapping linux kernel such
as the Woody installer boot-floppies 2.4.18-bf24 kernel may need to
specify driver modules to be loaded for their hardware when
upgrading to the newer moduler 2.6 series kernel. The 'discover'
and 'hotplug' packages are useful to detect hardware and to
automatically load the required modules. It is recommended to
install those packages prior to upgrading to a linux 2.6 kernel.
The 'udev' package is also useful in conjunction with the linux 2.6
kernel the /dev directory. But see the warnings below in the
section "Switching to 2.6 may activate udev" for more detail.
Anyone installing a new Debian installation using the new
debian-installer will get discover and hotplug installed by default.
It is a new installation without any history. The installer puts it
there by default. After that further customization is allowed by the
So this problem really only affects upgrades from a non-modular kernel
to a modular kernel. I can't say most but everyone *should have*
upgraded to a modular kernel in Woody and manually specified the
drivers they needed in /etc/modules. But for those that didn't and
are now upgrading from Woody to Sarge and find that all of the kernels
in Sarge are modular they are now finding this problem on upgrades.
