Officially linuxppc-2.4 is the official tree ;-) But  then  it  seems
that  there  is  still a lot of difference between linuxppc_2_4_devel
and linuxppc-2.4, and I think you can find new features in both trees
that are not (yet?) present in the other tree.

I guess Wolfgang Grandegger is aware of this. His other email address
is <wg at> :-)

But there are so many other trees. There is things like  the  ameslab
tree or the Linux-Tiny Tree or CELinux source tree or ...

Our linuxppc_2_4_devel tree is in sync with the BK linuxppc_2_4_devel
tree. But there is lots of additional stuff in out  tree  that  never
made  it into the "official trees". So many of our contributions were
rejected or delayed or ignored that I finally gave up.

Indeed. But I think this is as likely as a world without war :-(

I would be perfectly happy if there was some plan or roadmap or  just
a  description of the current state which says which tree is in which
state, if it is maintained and by whom,  and  how  long  it  will  be
maintained, and when or why or by whom it might be declared as "dead"
(as  happened  with  the  linuxppc_2_4_devel  tree), or if anybody is
actually taking care of the known problems, and when, etc.

Best regards,
