Well, ...

Currently i see only three ways to handle .udebs out of out of tree modules :

  1) have the kernel and modules .udebs be built from the main linux-2.6
  infrastructure, and thus export the .udebs flavours in the same way the .deb
  flavours are exported. This is not the choice of the d-i team, and altough i
  disagree with them on that, their opinion counts more on this. Furthermore,
  i believe that the dpkg and co problems which led to the splitting of the
  .udeb packages are not yet solved, and it is thus too late in the etch
  release process to go this way.

  2) do not build module .udebs from out-of-tree packages, and let it be the
  responsability of the d-i team to extract choice modules from those
  out-of-tree modules .debs to be repackaged as .debs. I don't know if the d-i
  team is ready to go that way, or thought of it.

  3) have some kind of .udeb meta package export the list of .udeb flavours.
  This is difficult in the current setup, since the flavour lists are
  distributed on all the per arch packages though, and i don't know if the d-i
  team is ready to change that, or if it is even technically possible, without
  going on the road to 1). Maybe a sub-1), with a single .udeb counterpart to
  linux-2.6 (linux-2.6-udeb) controlled by the d-i team would be an alternative,
  i don't know, if the dpkg and co problems can be solved though.

Anyway, these are the alternatives as i see them, i could have missed some
issues or possible solution, but i hope that this list will help everyone
involved see the situation clearly, even those not aware of the older
situation which gave the birth of kernel-wedge, or the controversy surrunding
the build .udebs from the common linux-2.6 package, and take a good decision
on this issue.
