#Proxmox question: can I run it on a single node without a second node or separate backup server?

Edit: answered here in 2021: https://forum.proxmox.com/threads/using-proxmox-from-single-pc.98354/

Tldr: yes, and you can install a desktop manager to access the web gui, but some things are only configurable using the cli.

I'd like to start like this but be able to add nodes later, and learn a bit in the mean time. To begin I'll just be running Home Assistant without internet and at some point setup remote access.
