I have done some experiments on my server in the past. It's a great way to learn new things. However, I am bound to make some mistakes and over time the sever becomes messier and messier.

A week ago I installed UNRAID on my machine and I love it! I can now have my critical infrastructure live and working in docker containers and vms.

Then if I want to do an experiment I spin up a VM in a couple of minutes to do my thing and remove it when I am done. No traces left!
