== Overview ==
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
TuneD profiles:
* can be defined hierarchically, which reduces duplication and simplifies maintenance:
More specialized profiles can inherit generic profiles and just change what is needed instead
of duplicating the code. For example, you can built a generic profile for HTTP server upon the
throughput-performance profile and later create two more specialized profiles for the Apache
server and the Nginx server, basing both profiles on the generic HTTP server profile.
* support full rollback:
The system can be easily returned to the state before the profile was applied. This can be
handy for testing, benchmarking, experimenting, and so on. For example, you can set up a cron
rule to apply a certain profile during business hours and a different one at night.
* include a number of predefined profiles for common use cases:
For example, presets for high throughput, low latency, or powersave are distributed. Profiles
optimizing performance for various products like SAP, dBase servers, and so on are also
provided, and it is possible to fully customize them.

= Requirements =
1. Availability
* Package is in universe: https://launchpad.net/ubuntu/+source/tuned
However, there is another separate package in LP with the same name:
https://launchpad.net/tuned
* The version of tuned in Universe for Jammy is 2.15. However, we are requesting version 2.18 due to known bugs in 2.15 that are fixed in 2.18.
2. Rationale
* The tuned package contains a daemon that tunes system settings dynamically. It does so by
monitoring the usage of several system components periodically. Tuned allows users to select
profiles based on workloads, one being real-time. A user can enable the real-time profile,
which has shown to reduce latencies.
* The tuned package is already in use by end users running CentOS and looking to move to Ubuntu.
* Example of using the real-time profile compared to default Ubuntu real-time kernel. Notice the
last column, which is the max latency:

3. Security:
* The only security issues found in the NVD are for versions 2.10 and older. Tuned is Universe
is currently 2.15.
4. Quality assurance:
* Manual is provided
* No debconf questions higher than medium
* No major outstanding bugs.
Bugs outstanding:

1774000 Fails to boot cirros QEMU image with tuned running
1838063 not start "tuned-gui"

1925765 [21.04 regression] tuned breaks networking in podman containers
* Exotic Hardware: N/A
* No Test Suite shipped with the package
* Does not rely on obsolete or demoted packages
5. UI standards:
* This is a CLI tool. Tool has normal CLI style short help and man pages
* No desktop file required as it is a CLI tool.
