We are doing a:
[Unit] Description=CPU powersave [Service] Type=oneshot ExecStart=/usr/bin/cpupower idle-set -D 0 ExecStart=/usr/bin/cpupower frequency-set -g performance [Install] WantedBy=multi-user.target
chmod 644 /etc/systemd/system/cpupower.service; systemctl enable cpupower.service
on SLES12.3 machines, but after reboot this doesn't sets them!
It will only get set if we do a "systemctl restart cpupower.service" manually..
The Question: how to make it permanent, so it will be set after every reboot?
