Multiversion kernel package handling with 'purge-kernel.service'
This document (000021728) is provided subject to the disclaimer at the end of this document.
Environment
SUSE Linux Enterprise Server 15
Situation
Updating or installing kernel packages increases file system usage.
Resolution
Systemd service 'purge-kernel.service" need to be installed and enabled
(default for a new installation)
To enable:
systemctl enable purge-kernel.service
Config file /etc/zypp/zypp.conf need to have the following lines:
(default for a fresh install - see comments in config file)multiversion = provides:multiversion(kernel)multiversion.kernels = latest,latest-1,running
After a reboot, kernels exceeding configured numbers are beeing purged.
If a reboot is not possible the cleanup can be performed manually:
systemctl start purge-kernel.service
Cause
Old kernel packages will not be removed, which may cause the disk to fill up and therefore may cause operational problems later on.
