I am using Dietpi as a VirtualBox image since it is easy for me to configure. I only have a Windows 10 pro machine and I also use it as homemedia server. The wifey does not like Linux, so I cannot run Linux on it. At the same time, my PC spec is not that great, or you can say a potato PC.
It is an Intel® Core™2 Quad CPU Q6600 @ 2.40GHz 8 GB RAM. Even though it is a potato with Windows running on it, I can manage to run two Dietpi virtual boxes, one running for Pihole and the second for Docker.
The Pihole ran for maybe around 3 years, and there was no problem. While for the docker, I keep changing it and rebuilding it since sometimes I messed up with the docker, so I just rebuilt it because DietPi is easy to deploy and fast. Even with that potato, in under 8 minutes, including setting the IP, local host, region, install docker, Portainer, NPM, etc. I can have a fresh install Dietpi with docker ready to use. That’s why I never worry to make mistakes on my docker VM.
That is my experience with Dietpi and the reason why I am still using it, so in my opinion, you can try it. Who knows it will fit your need.
But do you know which group in particular? I know there is alt.reddit.usenet but it is not a lot of message for now.
