Will you have to generate the config files here using the diff files?
generate default (=i486) config
How do you generate this one? According to one of your last mails it
should already exist as Bering_KRELEASE_.config.

Another manual intervention on all of the arch files which will need to
be generated from the diff files.

You see here, you generate configs and recreate diffs, I don't think
this step is necessary, but in the end the results should be the same,
IHMO just too much work and could be avoidedd.
If we really could just work on the default config and the diff
mechanism would allow us to upgrade all existing archs automatically
then I would be all for it. But to me right now, this assumption appears
to be wrong.

I never said it was hard, just some steps might not be necessary
