Solaris 10: Starting with the Solaris 10 release, the functionality of the patchadd -M command is improved to enable more effective and efficient handling of multiple patches and dependencies between patches. As a result, you no longer have to specify patch IDs in numerical order when using this command.
Note that if you use the patchadd -M command without specifying a patch ID or patch IDs, all the patches in the directory are automatically installed on the system. To install a specific patch or patches, you must specify the patch ID when using the patchadd -M command.
For more information, see the patchadd(1M) man page.
