For a headless 64-bit server setup, why do you recommend DietPi over the “official” RaspiOS Beta?
Hardware: RaspberryPi 4B (8GB)
DietPi is not an own OS, it’s a set of scripts on top of a base image. In case of Raspberry Pi, we use Raspberry OS as base. But in an extreme slim/diet version. Means in case of 64bit, we use Raspberry OS 64bit Beta. Officially Raspberry OS 64bit has not been released as stable by Raspberry Foundation.
In comparison DietPi is booting faster, uses less memory as well as less disk space.
