We are happy to announce the creation of a new family of Fedora Linux spins: Fedora Atomic Desktops! As Silverblue has grown in popularity, we’ve seen more of our mainline Fedora Linux spins make the jump to offer a version that implements rpm-ostree. It’s reached the point where it can be hard to talk about all of them at the same time. Therefore we’ve introduced a new brand that will serve to simplify how we discuss rpm-ostree and how we name future atomic spins.↫ Joseph Gayoso for Fedora Magazine
You can get pretty much any major desktop environment as an rpm-ostree (inaccurately referred to as ‘immutable’) version of Fedora, so it makes sense to standardise the naming scheme.
