updmerge - Merge customized and user files with newly installed files
/usr/bin/updmerge [-r] directory /usr/bin/updmerge directory /usr/bin/updmerge file directory
Performs a recursive reinstallation of all the files and subdirectories in the /var/adm/install/update area relative to the specified directory.
Specifies the directory from which the reinstallation is relative. This is typically the root (/) directory. Specifies the name of a file in the update area, or specifies the relative pathname of that file from the update area.
The updmerge utility is a part of the Reinstallation Toolkit (RITKIT). This utility enables you to merge files that have been preserved from a previous installation into the new installation environment. Thus, any user file or customized file from a previous installation that you do not want replaced or overwritten can be saved and reintegrated into a new installation environment.
You must have superuser privileges to invoke this utility, the system must be in single-user mode, and this utility must be invoked from the /var/adm/install/update directory. This directory is created by the updmv utility. It contains the files that have been preserved from the previous installation.
To integrate files from the previous installation into the new installation environment, the updmerge utility compares each preserved file to the newly installed files as follows: If the preserved file does not exist on the system, you can view the preserved file before determining whether or not to install it. If the preserved file does exist on the system, you can view the differences between the preserved file and the newly installed file before selecting the file you want installed on the system. If a preserved file is identical to a newly installed file, a message is printed to this effect and the next file is checked.
The updmerge utility is invoked as follows: To perform a recursive installation of all preserved subdirectories under the /var/adm/install/update area relative to a specific directory, specify the -r flag followed by the directory parameter. To install only those preserved files directly under the /var/adm/install/update directory, specify only the directory parameter. This causes a non-recursive merge of the files in the specified directory. By using this parameter, subdirectories in /var/adm/install/update are not merged into the new installation environment. To install only a single preserved file, use the file parameter followed by the directory parameter. A file can be the name of the file in the /var/adm/install/update directory, or it can contain the relative pathname of that file from the /var/adm/install/update directory.
In this example, the updmerge utility recursively installs all preserved subdirectories and files under /var/adm/install/update relative to the root (/) directory: updmerge -r / In this example, the updmerge utility installs the preserved /etc/hosts file relative to the root (/) directory: updmerge etc/hosts / In this example, the updmerge utility installs the preserved files in the etc directory relative to the root (/) directory (in this case, /etc): updmerge etc /
Storage area created by the updmv utility that contains the files preserved by RITKIT.
