So instead of having 5 module udebs for my ONE generic kernel I get
200? For say amd64 it would be a big step back.
How many archs with flavours are we talking about anyway? I think m68k
has 3 flavours and ppc some and every other archs has a generic
flavour or drivers buildin already.

All my hardware (that includes m68k) has absolutley 0 problems with
that. They will be installed in D-I and they will be installed on the
finished system. No point breaking my neck to get less installed

So why then do you want to split module udebs?
You just agreed that downloading the module udebs is inconsequential
given their size. You agreed that more udebs increases the Index files
which is bad.
So all I'm left with is that you don't end up with as much modules in
the ramdisk. Something I find irelevant unless you talk about the
Is the space taken up by the installed modules your actual argument

Last I used it, and that is some time ago, the dependencies where
automatically checked on build. Maybe someone broke that but that
could be repaired easily enough.

The indirection is that every change in the module split needed by the
D-I team would have to through the kernel-team and would require a
full source upload with days of buildd time. Which is quite insane
just to move a module from package A to package B so the floppy image
doesn't overflow while things get worked out.

Which in no way garanties that there is such coordination. The need
for coordination in the D-I team is just as great as in the kernel-team.

Well, YOU do and you are part of the kernel team.

I would rather have 7-day uploads and have the kernel DFSG free and
distributable. Two things that it is not and known since before sarge

No it isn't. The GPL only requires that you have the source and that
is available via the linux-tree package even for past versions no
longer in the archive.

You assume knowledge about past discussions. You should have included

The only thing I believe is that you acting wrong NOW and you keep
acting wrong NOW. I wasn't involved in your D-I incident and I refuse
to be drawn into it.

You loose any chance of getting back in or anyone listening to you.
And just to let you know, from now on I will ignore all mails that
include the D-I incident or you being mistreated. If you can't keep
to the technical discussion then I'm sorry but I want to do some
productive work and not wallow in self pitty (be that justified or not
I simply don't care).
