Among many new enhancements for managing IPS package repositories is the ability to automatically mirror remote repositories locally using an SMF service, svc:/application/pkg/mirror. This service helps you create local IPS package repositories and keep them in sync with Oracle hosted public IPS package repositories.
Additionally, you can use a new pkgrecv --clone option to exactly clone a package repository while preserving timestamps.
See Copying a Repository From the Internet in Copying and Creating Package Repositories in Oracle Solaris 11.2 for more information.
