Chapter 5. Cloning Software Channels and Errata
Use the
spacewalk-clone-by-date command to create custom cloned Red Hat Enterprise Linux channels based on the date an erratum was made available to the Red Hat Enterprise Linux system.
5.1. Features
The following features are available with
spacewalk-clone-by-date:
- Cloning the channel errata and associated package states as they were on a specific date
- Automating the cloning by scripts and template files
- Removing or blocking packages from channels
- Resolving package dependencies within the parent and child channels
- Filtering and acting on specific errata while ignoring others. For example, acting only on security errata and ignoring bugfixes and enhancements.
Note
You need to run the
spacewalk-clone-by-date command as the root user and the username needs to be either an Organizational Administrator or Channel Administrator.
Important
Use of
spacewalk-clone-by-date is limited to Red Hat Enterprise Linux 5 and higher versions because spacewalk-clone-by-date uses yum metadata to complete dependency resolution. Red Hat Enterprise Linux 4 and lower versions use the up2date command to install and update packages and does not provide the metadata spacewalk-clone-by-date requires.
