Greetings,

If you use AI to install and use the default manifest that comes with AI, 
please continue, otherwise please ignore.

With changeset 1105:f611cbe233ce 
<http://indiana-build.us.oracle.com:8080/rev/f611cbe233ce> that Jack just helped me 
put back into slim_source to address bug 7014749 
<http://monaco.sfbay.sun.com/detail.jsf?cr=7014749>, installation of Solaris using AI 
have changed as follows:

   * The default AI manifest <software_data> install section now specifies the 
server_install cluster package instead of slim_install
   * The <software_data> uninstall section which was used to list cluster 
package(s) to be uninstalled from the system has been removed.

Read on if you want more details..

The change from slim_install to server_install is done to address the immediate 
issue of missing IB drivers intentionally not included in slim_install, more 
over it is done to address other issues that might crop up due to the nature of 
slim_install pkg that is designed more for desktop use and includes very 
minimal server-oriented drivers/tools/utilities.

The second part of the change addresses life-cycle manageability of the 
software packages installed on a system. By definition cluster pkgs should not 
be removed because they provide grouping for the different individual pkgs and 
facilitate a seamless upgrade mechanism. They insure that all individual pkgs 
get upgraded at the same time and can be kept in sync. Until recently it was 
not possible to remove individual pkgs without removing the cluster pkg which 
depends on the individual pkgs, so we have been removing group pkgs to allow 
customization at the individual pkg level.

The removal of an individual pkg while having its cluster pkg around is only recently possible with 
the addition of pkg(5) "avoid". AI is taking advantage this new feature in its default 
install manifest by leaving group pkgs around post installation. If customization or removal of 
installed pkgs is needed post install, please refer to pkg(5) man page, specifically on 
"avoid" option.

Note: there will be more changes across all the Distribution Constructor 
manifests to take advantage of pkg(5) avoid which will be done through another 
bug.
