The Void (Linux) distribution

Void is a general purpose operating system, based on the monolithic Linux® kernel. Its package system allows you to quickly install, update and remove software; software is provided in binary packages or can be built directly from sources with the help of the XBPS source packages collection.

It is available for the Intel x86®, ARM® and MIPS® processor architectures; Software packages can be built natively or cross compiling through the XBPS source packages collection.


Not a fork!

Void Linux is an independent distribution, developed entirely by volunteers.

Unlike trillions of other existing distros, Void is not a modification of an existing distribution. Void's package manager and build system have been written from scratch.

Rolling release

Install once, update daily. Your system will always be up-to-date.

Thanks to our continuous build system, new software is built into binary packages as soon as the changes are pushed to the void-packages repository.

runit

We use runit as the init system and service supervisor.

runit is a simple and effective approach to initialize the system with reliable service supervision. See the usage page for a brief introduction.

LibreSSL

We were the first distribution to switch to LibreSSL by default, replacing OpenSSL.

Due to the Heartbleed fiasco we believe that the OpenBSD project has qualified and pro-active developers to provide a more secure alternative.

xbps

xbps is the native system package manager, written from scratch with a 2-clause BSD license.

xbps allows you to quickly install/update/remove software in your system and features detection of incompatible shared libraries and dependencies while updating or removing packages (among others). See the usage page for a brief introduction.

xbps-src

xbps-src is the xbps package builder, written from scratch with a 2-clause BSD license.

This builds the software in containers through the use of Linux namespaces, providing isolation of processes and bind mounts (among others). No root required!

Additionally xbps-src can build natively or cross compile for the target machine, and supports multiple C libraries (glibc and musl currently).

The Advent of Void: Day 13: feh

Sometimes you just want to view an image and do so quickly. Using a full desktop image viewing package may be too slow or too cumbersome, or if you’re in a minimalist environment might bring in too many extra packages.

In these cases, feh is the ideal tool for the job. This simple image viewer understands most common formats and can be called from the command line.

For example:

$ feh imgs/security_architecture_unredacted.png

Its really that simple! Just pass a single file or a directory to the command and it will display in a new window.

Displaying images isn’t all that feh can do though, you can also use it to set desktop wallpaper in a window manager only environment. In this use case, most users will find the --bg-scale option to be the appropriate choice as it will preserve the aspect ratio of the images used. There are other options as well, and these can be found in the man page.

Once used once to set the desktop wallpaper, feh will write a script ‘.fehbg’ to your home folder which can subsequently be called to set the wallpaper. This script is suitable to add to startup scripts or other initialization mechanisms so that you always have your favorite wallpaper after logging in.

Whether its quickly looking at images from the command line, showing a slideshow of vacation pictures, or setting the desktop wallpaper, feh is a must have utility for speedy image handling!

The Advent of Void: Day 12: redshift

If you stay up late working on packages and system security patches, you may notice after a while your eyes start to hurt. This is likely due to too much blue light at night, which studies have shown can cause eye strain. While glasses and monitors that can filter this light out are one solution, you can also adjust values in software to account for this blue light at night.

Doing this by hand is obviously tedious, so there’s an excellent software package called “redshift” which does this adjustment for you.

Once installed from the repos (xbps-install redshift) create a file like so that configures it:

[redshift]
temp-day=5700
temp-night=3200
gamma=0.8
location-provider=manual
elevation-high=24.69

[manual]
lat=39.109489
lon=-76.772980

This file should be in ~/.config/redshift.conf

The fields are pretty self explanatory, with the exception of elevation-high which is the solar elevation in degrees before its considered to be daytime. All temperatures are provided in Kelvin, and the wikipedia page on color temperature has a nice chart showing different values against the common sources of light that produce them.

From here, just start redshift with your session (redshift-gtk if you have an environment that can autostart .desktop files) to enjoy color filtered light at night!
