TuneD is a system tuning service for Linux. It:

• monitors connected devices using the udev device manager
• tunes system settings according to a selected profile
• supports various types of configuration like sysctl, sysfs, or kernel boot command line parameters, which are integrated in a plug-in architecture
• supports hot plugging of devices and can be controlled from the command line or through D-Bus, so it can be easily integrated into existing administering solutions: for example, with Cockpit
• can be run in no-daemon mode with limited functionality (for example, no support for D-Bus, udev, tuning of newly created processes, and so on) for systems with reduced resources
• stores all its configuration cleanly in one place – in the TuneD profile – instead of having configuration on multiple places and in custom scripts
