There’s a separate command called visudo for this purpose.
You CAN use any ol’ text editor but visudo has built-in validation specific to the sudoers file. This is helpful because sudoers syntax is unique and arcane, and errors are potentially quite harmful.
Weird. That used to say “container-native”, which at least makes sense – it heavily emphasizes container technologies like Flatpak, Docker/Podman, and Distrobox.
There’s no yum or dnf like on a standard Fedora system (though you can use rpm-ostree if you are desperate). As an “immutable” distro, it’s designed so that you do not install apps at the system level.
It used to say “container-native”. They recently changed the wording, but there was no technical change.
It’s a Linux distro that runs locally, like any other. It has no particular tie-in with any cloud services. If Flatpak, Docker/Podman, Distrobox, Homebrew, etc. are “cloud” just because they involve downloading packages hosted on the internet, then I don’t know why you wouldn’t call “traditional” package managers like apt, dnf, zypper, etc. “cloud” as well. 🤷 So yeah, I feel your confusion.
The big difference compared to something like Debian or vanilla Fedora is that Bazzite is an “immutable” distro. What this means is that the OS image is monolithic and you don’t make changes directly to the system. Instead, you install apps and utilities via containers, or as a last resort you can apply a layer on top of the OS using rpm-ostree.
The only thing cloud-related about any of this is that atomic OS images and containers are more common in the server space than the desktop space.
