Home Server/SBC Operating Systems
If you are using an SBC or NUC for your server, these are potential options to use over standard (GNU/)Linux distros.
DietPi
Extremely lightweight, extremely optimized version of Debian, and best of all, extremely easy. Can be installed on any SBC. Comes with a software centre with automatic configuration and optimization for your hardware, maximizing performance. CLI-based, but very retard-friendly and includes some nice menu systems.
FreedomBox
Runs on virtually any SBC.
Setup is incredibly simple. Installing new software and services can be done with the click of a button.
Lets you easily share files, host websites, sync files, and more. The number of available applications are a bit limited however.
YunoHost
Debian-based. Like FreedomBox, incredibly simple.
