Bazzite is an alternative OS to SteamOS for the deck and other handheld PCs. Unfortunately due to a mistake, anyone who installed Bazzite before July 3rd 2024 won’t get automatic updates.
If this affects you, I’d suggest checking out the article to get instructions on fixing it.
Yep, distrobox is a wrapper for Podman, which is also installed by default.
But I agree, there’s actually not a ton of functional difference between SteamOS and Bazzite, unless you want/need to use your Deck like a laptop. If you are only doing gaming, SteamOS is actually the better choice, because Valve has patches and modifications that aren’t yet included in upstream that maximize the hardware’s capabilities and stability.
