mdadm is a tool for managing Linux Software RAID arrays. It can create, assemble, report on, and monitor arrays. It can also move spares between raid arrays when needed.

PRoot is a user-space implementation of chroot, mount --bind, and binfmt_misc. This means that users don't need any privileges or setup to do things like using an arbitrary directory as the new root file system, making files accessible somewhere else in the file system hierarchy, or executing programs built for another CPU architecture transparently through QEMU user-mode. Also, developers can use PRoot as a generic process instrumentation engine thanks to its extension mechanism. Technically PRoot relies on ptrace, an unprivileged system-call available in the kernel Linux.

This utility can read or write specific registers or all the available registers of the EC supported by the ec_sys Linux driver.

libnetfilter_queue is a userspace library providing an API to packets that have been queued by the kernel packet filter. It is is part of a system that deprecates the old ip_queue/libipq mechanism.

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

This is the Linux kernel ACPI platform driver for the EC firmware on Purism Librem laptop computers. It allows user-space control over the battery charging thresholds, keyboard backlight, fans and thermal monitors, and the notification, WiFi, and Bluetooth LED.

Libnftnl is a userspace library providing a low-level netlink programming interface to the in-kernel nf_tables subsystem. The library libnftnl has been previously known as libnftables. This library is currently used by nftables.

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.

F2FS, the Flash-Friendly File System, is a modern file system designed to be fast and durable on flash devices such as solid-state disks and SD cards. This package provides the userland utilities.

This package provides two Linux kernel drivers, ddcci and ddcci-backlight, that allows the control of DDC/CI monitors through the sysfs interface. The ddcci module creates a character device for each DDC/CI monitors in /dev/bus/ddcci/[I²C busnumber]. While the ddcci-backlight module allows the control of the backlight level or luminance property when supported under /sys/class/backlight/.

The libnl suite is a collection of libraries providing APIs to netlink protocol based Linux kernel interfaces. Netlink is an IPC mechanism primarily between the kernel and user space processes. It was designed to be a more flexible successor to ioctl to provide mainly networking related kernel configuration and monitoring interfaces.

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.

This package provides the following binaries to drive the Linux Device Mapper multipathing driver:

1. multipath - Device mapper target autoconfig.

2. multipathd - Multipath daemon.

3. mpathpersist - Manages SCSI persistent reservations on dm multipath devices.

4. kpartx - Create device maps from partition tables.

ddate displays the Discordian date and holidays of a given date. The Discordian calendar was made popular by the "Illuminatus!" trilogy by Robert Shea and Robert Anton Wilson.

libnvme provides type definitions for NVMe specification structures, enumerations, and bit fields, helper functions to construct, dispatch, and decode commands and payloads, and utilities to connect, scan, and manage nvme devices on a Linux system.

mbpfan is a fan control daemon for Apple Macbooks. It uses input from the coretemp module and sets the fan speed using the applesmc module. It can be executed as a daemon or in the foreground with root privileges.

This package contains Advanced Linux Sound Architecture topology configuration files that can be used for specific audio hardware.

This package provides a program to generate an ext2 file system as a normal (non-root) user. It does not require you to mount the image file to copy files on it, nor does it require that you become the superuser to make device nodes.

The reform2_lpc module allows for interaction with the NXP LPC11U24 Cortex-M0 MCU system controller in the Reform 2 open hardware laptop. It provides battery status information and is necessary to completely shut down the system when powering it off via userspace.

This library provides APIs to access the Linux kernel's trace file system.

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 Python scripts in this project generate a GTK-UI to change TLP configuration files easily. It aims to protect users from setting bad configuration and to deliver a basic overview of all the valid configuration values.

LVM2 is the logical volume management tool set for Linux-based systems. This package includes the user-space libraries and tools, including the device mapper. Kernel components are part of Linux-libre.
