First of all, thank you very much for your reply, Oliver!

I am not really sure whether we are really talking about the same issue.
Since english is not my native language, I am pretty much sure I am the
cause of the confusion.

I try to express my understandings.

- You are talking about the split into separate packages because of
  license issues (which is pretty much OK, AFAICS.  There is no sensible
  way to get around that).  IMHO, nobody in this thread ever opposed
  this.

- I was talking about how to get the sources which are required to
  regenerate the original kernel binary that is distributed along with
  gutsy.  IMHO, the ability to get the source of the binary is the very
  intent of GPL.  As I wrote above, I am pretty much sure it is _not_ by
  intent.  To be honest: I am pretty much sure the problem is on my side.
  I simply have not (yet) figured out how regenerate the binary.  I have
  never said that anybody intentionally keeps me from compiling my own
  kernel.  The intent of my post was to eliminate my own errors in the
  kernel build process and find out the actual instructions how to do it.

I am very sorry for the confusion that I caused by not properly express
my question!

License issues again.  You have a very good reason to do this.  And
AFAICS, nobody ever criticized that.  The only critique was that there
is no explanation to be found how to regenerate it from the sources.

Ough!  I am very sorry if you understood it this way!  Really, I never
had the idea that it is a political decision.  My idea was that it is
either me (not understanding how to properly compile) or it is an
accident (the kernel team by accident packaged the wrong version of
the sources into the package or some such)

Please don't get confused.  There are _two_ wolf's involved in this
thread.  There is "Wolf Canis", and there is "Josef Wolf" (that is me)

I am not really sure.  Is -lowlatency really identical to
low-latency-desktop?
