10 Prepare a disk for cloning with the system cleanup tool #
The clone-master-clean-up tool that ships with SUSE Linux Enterprise Desktop makes it possible to remove data from the disk that you do not want to include in a clone. This chapter describes how to use the tool.
10.1 Cleaning up unique system identifiers #
As the cleanup tool removes essential system configuration data, it is not recommended to use it on a system that is used in production. Run the tool on the cloned image instead.
The clone-master-clean-up tool removes the following data:
swap files
Zypper repositories
SSH host and client keys
temporary directories, like
/tmp/*Postfix data
HANA firewall script
systemd journal
To install clone-master-clean-up, run the following command:
>sudozypperinstall clone-master-clean-upConfigure the tool by editing the
/etc/sysconfig/clone-master-clean-upfile. Here, you can specify which specific data the tool should remove.Run the script to perform a cleanup:
>sudoclone-master-clean-up
