This assumes that the diff takes into account all of the changes that
have been made. Unfortunately, if you apply that diff to a virgin 2.1R
tree you won't get the same tree as a 2.1.5 tree due to
removal/additions and such. The only *safe* way of doing this is to
start with a 2.1R CD and build a set of patches from it. Unionfs would
be great for that. :)
