For patch operations initiated from within Oracle Solaris 10 Zones, if the remote system is another solaris10 zone, the patching operation works correctly. However, if the remote system is a miniroot or an Oracle Solaris 10 system that is not a solaris10 zone, the operation will produce undefined results. Similarly, the patch tools will produce undefined results if used to patch Oracle Solaris 10 Zones from miniroots or physical systems instead of Oracle Solaris 10 Zones.
Note that in general, the patchadd and patchrm tools allow administrators to specify alternate roots when running patch operations. This capability allows administrators to patch remote systems, such as Oracle Solaris 10 miniroots and Oracle Solaris 10 physical systems, which have root directories visible over NFS. For example, if the root directory of an Oracle Solaris 10 system is NFS-mounted onto a local system's /net/a-system directory, then the remote Oracle Solaris 10 system could be patched from the local system.
To install patch 142900-04 (or later version) on the remote system:
# patchadd -R /net/a-system 142900-04
