OS/390® V2R5 (or later) SMP/E provides facilities to simplify the installation of cooperative or client/server products (such as OS/2). This is done with a common SMP/E packaging structure, a common S/390® server repository for client components, and a server repository accessible from any client platform. These facilities allow, for example, storing the client parts in a UNIX file system, which allows them to be packaged and installed along with the host parts, rather than separately.
