Hi Jeffrey-
   Thanks for the reply!

   That is about what I thought.  I guess I ask because for those of us who 
work more with AIX than the other platforms, it would be interesting and 
valuable to be able to track the IBM code base as well, even if that were kept 
in a separate repository from OpenAFS.

   I'm also very interested in what it took to clean the code base to achieve 
the 1.0 release.  I know some things were removed such as that washtool thing, 
and the special version of AIX's fsck that is AFS-aware.  But that was a long 
time ago.  I wonder if times have changed and if there would be fewer legal and 
technical hurdles to releasing some of those things?  The AIX AFS-aware fsck 
would be worthwhile even now.

   Anyway, thanks again!

-Ben

Hi guys-

   So I know IBM released the AFS code to the community at the beginning and 
that is what became OpenAFS.  But from various release notes on the IBM site, 
it would seem that IBM continued (and continues) to develop its own AFS 
internally as well.

   Does anyone know how far the IBM vs OpenAFS code bases have diverged?  I 
know they at least have more AIX ports than the OpenAFS code currently does...

IBM released OpenAFS 1.0 on 31 Oct 2000.   That release was a fork from IBM AFS 
3.6.  The fork itself at this point was substantial.  IBM had to clean the code 
base before it could be released.   The diff stat between these releases was 
not inconsequential.


IBM has continued development of IBM AFS 3.6.  There has been no effort to 
synchronize with OpenAFS.  They are very much independent creatures at this 
point.  Since the openafs-ibm-1_0 release OpenAFS has undergone substantial 
change


  6127 files changed, 1308387 insertions(+), 567306 deletions(-)

   Does anyone know anyone at IBM that could be asked if IBM would be willing 
to re-contribute it's current codebase?


Yes we know people and they know us.  It wouldn't be worth asking.    There is 
simply too much churn to merge code changes.

At best, concepts and features added to IBM AFS 3.6pXXX could be re-implemented 
in OpenAFS.
