I wish I knew. maybe nothing, I get some file already exists message. and then
the compilation fails with header files not found. Then I'm off on the same old
roundabout. Maybe if I was more organised I would make a list of the things I
had to change to make it work each time.

I did yes, and thanks for your help on that. The problem is it seems to take me
rather a long time to get it all going from one release to the next. I think my
troubles are related to using gcc 3 rather than 2.97

Thanks I'll look into CVS.

I don't want to impinge on your time too much with my particular problems, apart
from the fact that I should be perfectly capable of solving them myself(!) I
don't have as much free time as I would like for this sort of thing but I really
would like to help where I can.

I think it would help people who want to work on the userland code.

Another idea:
One think we do at work is to have a bitkeeper repository (though it could
equally well be done with CVS) of the whole Linux kernel with our modifications
applied. When a new kernel release happens then those changes are merged into
the CVS tree, so users sync with that and get a whole, (hopefully!) working
kernel tree.
