I use Fedora Kinoite daily and find it to be the only OS to make sense really.
I find Fedora CoreOS totally confusing (with that ignition file, no anaconda, no user password by default, like how would I set this up anywhere I dont have filesystem access to?)
But there are alternatives. I would like to build my own hardened Fedora server image that can be deployed anywhere (i.e. any PC to turn into a secure and easy out-of-the-box server).
As modern server often uses containers anyways, I think an atomic server only makes sense, as damn Debian is just a pain to use.
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.
I am completely confused about ublue currently, (okay all they did is remove the image list, its the same on Github)
Debian is old and crusty with all its tooling. Apt sucks, automatic updates are strange, there are no snapshots afaik, it uses ext4, its like Fedora was 10 years ago
People who use Debian servers typically just install Docker on a basic system and then use containers. Which is exactly the same concept that you describe.
What's the filesystem of the server got to do with anything? You can take snapshots in half a dozen different ways, everybody uses the method they're comfortable with.
A bunch of edgelord babies skimmed the selfhosted subs and noticed that "atomic distros" is a common buzzword ATM; they then flood said subs with opinionated posts that atomic subs are the best and everything else sucks 🙄
