Determine which software requires upgrading


Recognize the importance of balancing the need to keep software up-to-date while minimizing the impact on a production system. Dragonfly and NetBSD use pkgsrc which provides utilities for determining which installed software is out-of-date. FreeBSD provides pkg_version and third-party utilities are also available which integrate with the BSD package managers.
