Rollback
Before deploying the package into
an installation, the utility creates a rollback directory containing
the backup copy of files from the current installation which will
be used incase of a rollback action. You can rollback your configuration
to that in your rollback directory, only if the version of your current
installation is the same as the version of the installation when the
rollback directory was created.
Soft links created for product related files in the RHEL/CentOS environment are not
handled by sm_deploy utility.
