Removing a Solaris Patch

When you back out a patch, the patchrm command restores all files modified by that patch, unless:

• The patch was installed with the patchadd -d option, which instructs patchadd not to save copies of files being updated or replaced)

• The patch has been obsoleted by a later patch

• The patch is required by another patch

The patchrm command calls pkgadd to restore packages that were saved from the initial patch installation.

During the patch removal process, patchrm keeps a log of the back out process in /tmp/backoutlog.process_id. This log file is removed if the patch backs out successfully.
