This chapter gives an overview of the new features in the base operating system (BOS) installation and software installation procedures for AIX 5.2.
Installation options are available for you to configure your system during a BOS installation process.
The installation options include the following:
For information about the installation options, see Installation Options.
The Copy Software Bundle to Hard Disk for Future Installation option is available in the SMIT Software Maintenance and Utilities menu.

The SMIT Software Service Management menu allows you to manage how you update systems with fixes and preventive maintenance package levels. You can compare levels of different systems against a base system or a base set of fixes. Support is provided through the command line and SMIT to allow you to compare the filesets installed on your standalone system with the contents of an image repository or a service report that is downloaded from the IBM eServer pSeries support Web site.
This option also allows you clean up or rename software images in a repository. The following software maintenance options are available in the SMIT Software Service Management menu and the SMIT Software Maintenance and Utilities menu:
The Rename Software Images in Repository option allows you to rename software images with the PTF prefix to the fileset names generated by the bffcreate command. This allows you to determine exactly what updates are contained in a directory because the fileset name is recognizable.
The Clean Up Software Images in Repository option allows you to perform various tasks to clean up software image directories on standalone systems. This allows you to remove duplicate or unnecessary filesets from image repositories, easing management of the images and reducing the amount of space required to store them.
For information about the SMIT Software Service Management menu, see Software Service Management.
Alternate disk migration installation allows the user to create a copy of rootvg to a free disk (or disks) and simultaneously migrate it through Network Installation Management (NIM) to a new release level. Using alternate disk migration installation over a conventional migration provides several advantages:

The Universal Disk Format (UDF) allows you to manipulate files directly on the DVD-RAM media. The system backup image is an archived file composed of many files that cannot be manipulated. However, the installation packages and any files that are not contained in the backup image can be directly manipulated on the DVD-RAM. After the DVD is mounted, the files can be changed by using an editor, or new files can be copied to the DVD using the various copy and restore commands (such as the cp, mv, and restore commands).
