What Is a Linux Distribution?
A Linux distribution (or "distro") bundles the Linux kernel with system tools, a package manager and usually a desktop. They all run the same kind of software, but differ in how often they update, how long each version is supported, and who they're built for.
Not sure where to start? Linux Mint or Ubuntu for a first desktop, Debian for a first server, and Proxmox VE for a homelab.
What the Details Mean
- Based on
- The distro it borrows its packages and tools from. Guides for the base usually work on its children.
- Package manager
- The command or app that installs and updates software (for example
apt,dnf,pacman). - Release model
- Fixed: a new version every so often, then only fixes. Rolling: small updates all the time, never a big upgrade. Immutable: the system is read-only and updates as a whole image you can roll back.
- Support
- How long a version gets security updates before you must upgrade.
- Init system
- The first program started at boot. It starts everything else. Most distros use
systemd. - Hardware
- Very light / Light: fine on old PCs. Moderate: any computer from the last 10 years. Heavy: needs plenty of RAM or a dedicated machine.
