Distributions are versions of the Linux OS, which are developed by different organizations and groups. Programs and desktops available in one distro are often available in others.
Well updated and widely distributed distros typically have support forums. Users may ask questions, and search for previous questions which have been answered.
This is a Meritocracy
Our default OS base directory "/distribution/" is sorted by longest life cycle. This is to reward those distributions for their efforts, and present readers with the best choices immediately in their field of vision without having to scroll down the page.
Reasoning and Goals
1). Less time spent re-installing operating systems, as they are within their update support window longer.
2). Increased probability of better security, due to it being less of a pain to keep servers in a state of having current security updates.
3). Less burden upon IT department staff, so they are free to do other things.
4). Push re-installs a decade down the road for the next generation of techs to worry about.
5). Introduce students and researchers to stable and long term platforms which are good to use as a desktop, but at the same time are also suitable for the back-end of a turn-key production server.
