Chapter 1 Introduction

The Solaris 7 Maintenance Update 4 Release Notes explain how to install the Solaris^TM 7 Maintenance Update^TM 4 (MU4) software, a set of patches that have been tested together and packaged for easy installation. These release notes are for system administrators installing the MU4 software. If you need more information on general procedures for system administration, refer to the Solaris 7 System Administration Guide.

The Solaris 7 MU4 applies to all systems running Solaris 7 software and to all Solaris 7 locales. The installation automatically updates previously installed patches without regressing any patches that are resident on your system.

Maintenance updates are primarily designed to update the Solaris operating software to a known, tested patch-level. If you want to apply a particular patch, and only that patch, you should do so through your normal support channels.

The Solaris 7 MU4 contains bug fixes and performance improvements. If you intend to upgrade your hardware, use the Solaris 7 11/99 CD rather than the MU4 CD.

The name of this product is Solaris 7 MU4, but code and path or package path names may use Solaris 2.7 or SunOS^TM 5.7. Always follow the code or path as it is written in this document.
