That's no secret because IBM just told the world that fact in the z/VM
6.4
announcement letter. Alan could probably tell you more (if he's
allowed :-)), but my understanding (just reading what IBM has written)
is
that z/VM's z/OS-derived components support certain z/VM elements and
features using common, battle tested codebases. One notable example is
z/VM's LDAP client and server feature. The z/OS-derived components are
really for z/VM's own use. However, perhaps z/VM's preexisting
z/OS-derived
components would interest you, and perhaps IBM would be interested in
helping support whatever project you have in mind. No guarantees, of
course, but it doesn't hurt to ask.
It's more than that, Tim, and it's no secret. The LDAP client and server,
MPROUTE daemon, System SSL (used in the SSL servers), gskkyman, and the
program management binder are z/OS program objects running on CMS, not
ports. This is done so that we don't fork the source and duplicate the
build environment. I.e. it's a development and service process thing. But
it's only doable when the program is structured in a way that keeps
invocation of non-POSIX services in a separate entry point.
The binder is a powerful tool for manipulating program objects and
performing microsurgery on CSECTs. When the anesthetic wears off and the
program wakes up, it doesn't realize that some of its parts have been
replaced.
