Enable TuneD no-daemon mode

You can run TuneD in no-daemon mode, which does not require any resident memory. In this mode, TuneD applies the settings and then exits. However, note that this mode disables certain features, including D-Bus and hot-plug support, and rollback functionality for settings.

Before you begin

  • You have root privileges or appropriate permissions to modify the system configuration.

Procedure

  1. Edit the /etc/tuned/tuned-main.conf file with the following changes: 
    sudo vi /etc/tuned/tuned-main.conf
     
    daemon = 0
  2. Save and close the file.
  3. Restart the tuned service or reapply or switch profile: 
    # systemctl restart tuned
     
    # tuned-adm profile <tuned_profile>
  4. Verify the tuned status: 
    # tuned-adm active
     
    It seems that tuned daemon is not running, preset profile is not activated.
Preset profile: <tuned_profile>
