This simple daemon feeds entropy from the CPU Jitter RNG core to the kernel Linux's entropy estimator. This prevents the /dev/random device from blocking and should benefit users of the preferred /dev/urandom and getrandom() interfaces too.

The CPU Jitter RNG itself is part of the kernel and claims to provide good entropy by collecting and magnifying differences in CPU execution time as measured by the high-resolution timer built into modern CPUs. It requires no additional hardware or external entropy source.

The random bit stream generated by jitterentropy-rngd is not processed by a cryptographically secure whitening function. Nonetheless, its authors believe it to be a suitable source of cryptographically secure key material or other cryptographically sensitive data.

If you agree with them, start this daemon as early as possible to provide properly seeded random numbers to services like SSH or those using TLS during early boot when entropy may be low, especially in virtualised environments.

The CRDA acts as the udev helper for communication between the kernel Linux and user space for regulatory compliance.

Early OOM is a minimalist out of memory (OOM) daemon that runs in user space and provides a more responsive and configurable alternative to the in-kernel OOM killer.

The tool conntrack provides a full featured interface that is intended to replace the old /proc/net/ip_conntrack interface. Using conntrack, you can view and manage the in-kernel connection tracking state table from userspace. On the other hand, conntrackd covers the specific aspects of stateful firewalls to enable highly available scenarios, and can be used as statistics collector as well.

Since 1.2.0, the conntrack-tools includes the nfct command line utility. This utility only supports the nfnetlink_cttimeout by now. In the long run, we expect that it will replace conntrack by providing a syntax similar to nftables.

libnfnetlink is the low-level library for netfilter related kernel/userspace communication. It provides a generic messaging infrastructure for in-kernel netfilter subsystems (such as nfnetlink_log, nfnetlink_queue, nfnetlink_conntrack) and their respective users and/or management tools in userspace.

PowerTOP is a Linux tool to diagnose issues with power consumption and power management. In addition to being a diagnostic tool, PowerTOP also has an interactive mode where the user can experiment various power management settings for cases where the operating system has not enabled these settings.

The Advanced Linux Sound Architecture (ALSA) provides audio and MIDI functionality to the Linux-based operating system.

This package provides statically-linked e2fsck command taken from the e2fsprogs package. It is meant to be used in initrds.

acpi attempts to replicate the functionality of the "old" apm command on ACPI systems, including battery and thermal information. It does not support ACPI suspending, only displays information about ACPI devices.

Tmon is a tool to interact with the complex thermal subsystem of the kernel Linux. It helps visualize thermal relationships and real-time thermal data, tune and test cooling devices and sensors, and collect thermal data for further analysis.

As computers become smaller and more thermally constrained, more sensors are added and new cooling capabilities introduced. Thermal relationships can change dynamically. Their complexity grows exponentially among cooling devices, zones, sensors, and trip points.

Linux exposes this relationship through /sys/class/thermal with a matrix of symbolic links, trip point bindings, and device instances. To traverse it by hand is no trivial task: tmon aims to make it understandable.

Touchégg is an application that runs in the background and transform the gestures you make on your touchpad or touchscreen into visible actions in your desktop.

Kbd-neo provides the Neo2 keyboard layout for use with loadkeys(1) from kbd(4).

Libevdi is a library that gives applications easy access to EVDI devices provided by the evdi driver package.

acpid is designed to notify user-space programs of Advanced Configuration and Power Interface (ACPI) events. acpid should be started during the system boot, and will run as a background process. When an ACPI event is received from the kernel, acpid will examine the list of rules specified in /etc/acpi/events and execute the rules that match the event.

python-spython is a Python library to interact with Singularity containers.

Python-evdev provides bindings to the generic input event interface in Linux. The evdev interface serves the purpose of passing events generated in the kernel directly to userspace through character devices that are typically located in /dev/input/.

This package also comes with bindings to uinput, the userspace input subsystem. uinput allows userspace programs to create and handle input devices that can inject events directly into the input subsystem.

Headers of the Linux-Libre kernel.

GNU Linux-Libre is a free (as in freedom) variant of the Linux kernel. It has been modified to remove all non-free binary blobs.

FuseISO is a FUSE module to mount ISO file system images (.iso, .nrg, .bin, .mdf and .img files). It supports plain ISO9660 Level 1 and 2, Rock Ridge, Joliet, and zisofs.

Utility to detect differences between two audio files, encoded with SBC.

Blktrace is a block layer IO tracing mechanism which provides detailed information about request queue operations to user space. It extracts event traces from the kernel (via the relaying through the debug file system).

Util-linux is a diverse collection of Linux kernel utilities. It provides dmesg and includes tools for working with file systems, block devices, UUIDs, TTYs, and many other tools.
