Hi Greg,
After your previous reply on this thread we started considering to provide this
interface and framework/functionality through a userspace service instead of a
kernel interface.
The latest iteration on this evolving patch-set doesn’t have strong reasons for

- Background and problem
The System Generation ID feature is required in virtualized or
containerized environments by applications that work with local copies
or caches of world-unique data such as random values, uuids,
monotonically increasing counters, cryptographic nonces, etc.
Such application
