Because containers (Distrobox, Flatpak, etc.) are bae.
You can read my post I made a while ago for more information: https://feddit.de/post/8234416
Once you “get” image based distros, you probably never want to go back. Traditional distros just feel… off now for me.
Containerisation is the biggest strength in Linux, we use it all the time on servers, so why not on the desktop?
Atomic OSs just make more sense for me, not only because of security/ bug/ whatever reasons, no, also because they feel simpler and are pretty convenient and robust.
I made a similar post a few weeks ago.
I will try uBlue core and give you all a small update about it.
I feel similar about Debian. It’s a good distro for sure and I don’t have any issues with it for server use, but somehow, I still don’t like it somehow. RPM-/ OSTree based distros are more my taste, and I don’t even know why.
