Well instead of the find actually need something like: 

  tar cvf - --exclude SCCS --exclude mkbuildtree . | \ 
  tar -C../linux-2.6.8.1-xen -xvf - 

(to deal with non-existant directories in the desintation).

> cp -a xen/include/hypervisor-ifs linux-2.6.8.1-xen/include/asm-xen

And instead of the above can use: 

  cd ../xen/include 
  tar cvf - --exclude SCCS . | \ 
  tar -C../../linux-2.6.8.1-xen/include/asm-xen -xvf - 

which just ensures get rid of SCCS directories.

Otherwise basically works; I've put a patch in this form on 

 http://www.cl.cam.ac.uk/~smh22/linux-2.6.8.1-xen-patch

in case anyone's interested. 

We should probably update the nightly build scripts to dump one of 
these on the standard download page...
