You need a OR dependency, not to bring all of them. For example, for i386 this becomes: Depends: linux-headers-2.6-686 | linux-headers-2.6-486 | linux-headers-2.6-amd64 | ... All of this is very bad. We need a way to express “I need the headers installed for all installed kernel packages”. The idea of package groups only partially solves this; it guarantees the headers are upgraded with the image, but it does not provide a good way to install the *good* headers. For example, let’s say d-i installed the linux-image-2.6-amd64 image, because you have a 64bit CPU. If you install a package using dkms, and it pulls the headers. But which headers? APT is not clever enough to install the ones corresponding to an existing kernel image; it will just install the first one in the list. > Sure, but who said to get -all? At least getting -all guarantees that you have the correct one, so this is by far not the worst idea that has been thrown. Having a linux-headers-2.6-all package depending on the default version of -all would do the trick for most situations, I think. > apt-get is able to determine the architecture he's running on, right?

You cannot install packages in a triggered script, or in whatever way that will be determined from within a package itself. You need to get *all* the requirements through package dependencies so that it can go in a single APT run. Cheers, -- .''`. : :' : We are debian.org.
