+# Additional ExecStartPre commands for the k3s service in systemd
+# This dictionary can be used to specify additional ExecStartPre commands
+# for the k3s service. These commands will be executed before the main
+# service starts. For example, the command below removes the
+# cpu_manager_state file if it exists.
+#
+# Usage example:
+# k3s_service_exec_start_pre_vars:
+#   - "-/usr/bin/rm -f /var/lib/kubelet/cpu_manager_state"
+#
+# Note: The "-" prefix before the command ensures that systemd ignores
+# any errors that occur when executing the command.
