I think a second machine is way better than dual booting. Dual booting is a pain in the ass. I try to avoid rebooting the machine for any reason, its disruptive.
Better get an old cheap thinkpad or small PC. And you dont have to take the risk of learning about partitioning on your primary machine as first baby step. Keep your important stuff where its safe until such time as you are comfortable switching over.
I don’t know. both? probably? I tried a couple of things here and there. it was plain that bringing in docker would add a layer of obfuscation to my system that I am not equipped to deal with. So I rinsed it from my mind.
If you think it’s likely that I followed some “how to get started with docker” tutorial that had completely wrong information in it, that just demonstrates the point I am making.
