I absolutely love what the universalblue team has been doing. They are one of the few organizations that are truly dedicated to providing a first-class, enjoyable, batteries included linux experience on the desktop.

I truly believe that updates are seamless not just because of all the buzzwords about the underlying technology but because its made for people who actually use the system daily. They gate the fedora kernel and track breaking changes so you don't get them, and generally care about the user experience. If you want sensible gnome defaults and extensions they are there (or there to be disabled at the click of a button). If you want remote desktop streaming (sunshine/moonlight) its there. On the flip side, their distribution model also means no more need to keep track of out of tree kernel modules on upgrades (zfs, nvidia, waydroid even on Bazzite).

Now onto the post specifically: LTS from a CentOS Stream base seems interesting. Fedora is nice, and the universalblue team tames it 99%, but its edge can be a bit too bleeding sometimes. My only reticence with CentOS Stream though is that it is veering dangerously close to Red Hat proper which I am unsure how to feel about. I am eagerly awaiting when non-rpms distros will be able to use the same underlying technology Bluefin uses, and see how the space evolves. A debian base especially seems interesting in theory. There has recently been some progress on that front: https://github.com/bootc-dev/bootc/issues/865 https://github.com/bootcrew/debian-bootc
