Is incus-compose a part of the base system, or an add-on? How does it work on IncusOS if it's a command-line tool and there's neither a remote nor a local shell, only a web API? Does it provide a built-in way to automate container updates?

I've been using Incus for awhile now, but TIL there's an IncusOS.

Running Incus on a headless Debian 13 host using a Ryzen 2700 CPU with an uptime of at least 200 days, no issues. Really like the ability to seamlessly pass through a GPU on any container running the same kernel. Used to run ESXi, never looking back.

Haven't heard about it. I probably should give it a try.

I've used Incus, but not incusos for over two years now. Works well.

Stability is great, flexibility to do what I need is also great.

Also there are quite a few options for deployment, I use ansible.

I've been running IncusOS on a 10 year old Dell Inspiron 22-3263 with no issues for around a year now. The install process was straightforward, even for this older hardware. Administration is via an intuitive web GUI, and if you've ever used Ubuntu Micro Cloud, you'd already be quite familiar with the interface, as Incus is a fork of that, IIRC.

I want to upgrade to it from Proxmox when I eventually get a new processor. It seems perfect for my use case; proxmox is far too complex for what little I do with it.

Sounds neat but I would be worried about the no shell stuff, I run my things headless for the most part and like SSH and occasionally VNC access.
