9. Arch Linux
Arch is a lightweight and flexible Linux distribution driven 100% by the community. Similar to Debian, Arch uses a rolling release model so incremental updates eventually become the Stable release. You really need to get your hands dirty to understand the system and its functions, but in turn you get complete and total control of your system.
It uses its own package manager, Pacman, to install, update and manage packages.
If you want a lightweight operating system and really want to understand Linux use Arch! There’s a bit of a learning curve, but for the hardcore Linux users, this is a great choice.
Great for desktop and laptop. If you also have a small device such as a Raspberry Pi and need to stick a lightweight OS on it, you can’t go wrong with Arch.
