nine distros created especially for small niche users



When most people hear about Linux distributions they most likely think of Alternative operating systems to Windows or macOS, on distros like Ubuntu, Linux Mint, maybe 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 they 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.







If you don't want to upgrade to Windows 10, here are some Linux distros to replace Windows 7





These distros have their use, and its good to know its existence in case we need something like that someday. But to replace operating systems for personal use that serve for most regular operations, they do not go.



Drauger OS




Draugur



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 deliver the highest possible performance.



What's more includes a series of pre-installed packages to offer the widest compatibility with all types of video games. 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




Caine Distro Linux

The distro includes all kinds of forensic scripts and utilities to extract data from all types of devices, drives, servers, and computers, whether they use Windows, macOS, or even Android phones.

This system it is much more powerful than the usual web interfaces offered by your network devices, and lets you do things like assign IP addresses, change DNS settings, they can function as a proxy or VPN access point.



Tails




Tails



Tails is probably better known than many of the other distros mentioned in this article. It is a 'live' operating system, that is, does not install but runs from a USB stick or DVD.



The initials of its name mean "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.
