When most people hear about Linux distributions they most likely think of alternative operating systems to Windows or macOS , to distros like Ubuntu, Linux Mint, perhaps Arch or Fedora.
Complete systems to use on a day-to-day basis, edit documents, browse the web, consume multimedia content, etc. However, in the world of Linux what is left over are niches, and for almost any niche you can imagine there is a special distribution . These are just some of them.
It is important to clarify that all these systems are designed with one or more quite specific and determined purposes, and are far from being an alternative for those who are simply looking for a distro to use as their main system to do “normal” things.
These distros have their uses, and it ‘s nice to know of their existence in case we need something like that one day . But to replace personal use operating systems that serve for most regular operations, they do not go.
Drauger OS is perhaps the distro that inspired this article, it is a fairly new project that seeks to be a Linux for gaming and nothing else . Drauger is optimized at the level of the kernel and the desktop environment you use to provide the best possible performance .
It also includes a series of pre-installed packages to offer the widest compatibility with all types of video games . On the other hand, Drauger does not include almost any other tool that has nothing to do with gaming because it is intended only to be a secure gaming system built on Linux.
CAINE or ‘Computer Aided INvestigative Environment’ is an Italian distro specially designed for forensic investigation . The system includes a number of friendly software tools to assist digital researchers.
The distro includes all kinds of forensic scripts and utilities to extract data from all kinds of devices , drives, servers, and computers, whether they use Windows, macOS, or even Android phones.
Although it may not seem like it, Parted Magic is a Linux distribution, it can be run from a CD or a pendrive and nothing is installed on the disk. Now, Parted Magic is not an operating system as such, but a disk management tool .
Its utility is to offer everything you need to edit the partitions of your disks, copy, move, resize, recover lost data , even reset or change the Windows password, erase data safely and deeply, or recover files from devices that show read errors. Of course, it is not free.
Zeroshell Linux Router is a small Linux distro dedicated solely to managing routers and firewalls through a web interface . It is designed to run as Live CD or USB on servers, routers, or even on the Raspberry Pi.
It has no graphical user interface and everything is done through the browser. This system is much more powerful than the usual web interfaces offered by your network devices , and it lets you do things like assign IP addresses, change DNS settings, and can function as a proxy or VPN access point.
Tails is probably better known than many of the other distros mentioned in this article. It is a ‘live’ operating system, that is, it is not installed but runs from a USB memory stick or a DVD .
The initials of its name stand for “The Amnesic Incognito Live System” and it is basically a Linux distro designed especially for privacy . Tails forces all its connections through the Tor network, leaves no traces after using it because it doesn’t store anything on disks (unless you ask for it), and it also uses the most modern encryption tools for your online communications and for your files.
Kali is a special Linux distribution for pentesters , that is, for security researchers and ethical hackers. It includes the most advanced tools, and is maintained by Offensive Security, which also offers free online pentesting courses.
Discreete Linux is a distro specially designed to protect user privacy, specifically against surveillance that takes advantage of attacks via Trojans . It does so by offering an isolated environment without support for networks or internal disks, since everything is stored offline in the RAM memory or on a USB disk in an encrypted way.
It is mainly aimed at people who do not necessarily have great computer skills but who need to protect themselves enormously, such as journalists, human rights defenders, activists, etc.
RetroPie / Raspbian
RetroPie is not a Linux distro as such, but it exists as a layer that sits right on top of one and uses it to turn your Raspberry Pi into a retro video game console . That system on which it stands is Raspbian , a Linux distro created specifically for the Raspberry Pi.
RetroPie makes your Raspnerry become a mega emulator of old consoles , from the Amiga to the Game Boy, through the Dreamcast, to the Super Nintendo or the PlayStation 2.
Unlike RetroPie, Lakka is a complete and lightweight Linux distribution specially designed to turn your computer into a retro video game console .
Lakka is the official distro of the famous RetroArch emulator and libretro ecosystem. It is also designed for low-resource mini computers such as the Raspberry Pi, but you can install it wherever you want.
Puppy Linux is not a single Linux distribution like Debian. Puppy Linux is also not a Linux distribution with multiple flavours, like Ubuntu (with its variants of Ubuntu, Kubuntu, Xubuntu, etc) though it also comes in flavours.
Puppy Linux is a collection of multiple Linux distributions, built on the same shared principles, built using the same set of tools, built on top of a unique set of puppy specific applications and configurations and generally speaking provide consistent behaviours and features, no matter which flavours you choose.
