This should only happen when a new major version of the kernel comes
out, which means it should only happen in unstable..

And we could make it so that it is possible to make that particular
OOT skipped (manually or automatically after a specified time), and
hence won't be available for that run of d-i.

But within a oldstable or stable kernel, only the Debian version changes,
right, so...


But if a kernel changes a lot and often in unstable, support for that
specific OOT will be intermittent. Might not be a huge problem in unstable.
Unwanted, but not a huge deal...

Maybe even build them using dkms? I saw that you can make d-i build
all packages... So adding a extra hook or something that sees that this
is a OOT module, then get it's dkms package, build (to a .deb/.udeb
which I have patches sent upstream for) it and use that...


But either way would mean that the d-i builder have to do the fixing,
instead of a group of people (should be the responsibility of the
OOT module maintainer(s)).

What if an OOT is a network module? Might be needed before the network
is up to fetch it...

And if it's included in the monolithic image, then it will be up to
the d-i builder/uploader to make sure that the module is available,
not a group of people...
