On Solaris 10 package management was generally a pain, but there was a "sparse root" kind of zone that shares /usr with the global zone, so these get the updates automatically. http://solaris.reys.net/zones-in-solaris-10-part-three-sparse-root-and-whole-root/ http://solaris.reys.net/zones-in-solaris-10-part-three-spars... For OpenSolaris derived products with ipkg, the documentation says that "pkg update" in the global zone will update not only the global zone but all non-global zones as well. https://docs.oracle.com/cd/E26502_01/html/E28984/gmhaa.html https://docs.oracle.com/cd/E26502_01/html/E28984/gmhaa.html
