This appears as an attempt to install the same architecture and version of a package that is already installed. This installation overwrites this package.
The "Installing Solaris Software - Progress" bar sometimes indicates that an installation is complete when it is still in progress. The install program may add packages for several minutes after the progress bar has indicated that the installation is complete. Do not rely on the progress bar to indicate that the installation is complete. The installation displays the following message when the program has completed all installation operations:
When you upgrade the Solaris operating environment on a server with diskless clients, the options on the dfstab line are not preserved for /usr. For example, if you entered the following in the dfstab file:
share -F nfs -o rw /export/exec/Solaris_2.7_sparc.all/usr
then this entry is automatically replaced with the following entry during the upgrade:
share -F nfs -o ro /export/exec/Solaris_2.7_sparc.all/usr
Workaround: Before you attempt to upgrade the Solaris operating environment on an OS server that has a diskless client or Solstice AutoClient, back up the /etc/dfs/dfstab file for the clients.
