Really? Tomcat 6.0 replaced the server/lib/, shared/lib/, and
common/lib/ directories in favor of a single, unified lib/ directory.
That doesn't strike you as an important change?

There is a chicken-and-egg problem with the context ClassLoader which
makes it difficult for the container to set up the context using Java
classes that are hosted from within that application. Anything the
driver depends upon also needs to be available to the container's
ClassLoader.

I'm curious as to why you are using hard links instead of symlinks. If
you copy a new file over a hard link, you un-couple it from the rest
of the series of hard links. If you do the same with symlinks, the
result is probably more what you were expecting. There are other
disadvantages with hard links including not really knowing that it's a
link (symlinks are obvious) and they can't span across filesystems.
