Behind Bluefin is a project called Universal blue which is a whole bunch of people with many interests, but biggest one being DevOps, devOps combined with its "immutable", image-based nature which should make maintenance of distro lot easier then normal
I use plain old Debian now, but used to love some of the Debian based distros. CrunchBang springs to mind.
I tend to stick pretty close to defaults these days, so some scripts and Ansible playbooks configure everything on all of my machines with not a lot of maintenance or future worries.
I run Debian on all of my server stuff at home too. It's not a perfect desktop, but the consistency between machines is something I appreciate.
I use it as my stable base while running most applications from Flatpaks. They're up to date but the OS itself never surprises me.
At the end of the day it's just running a build step in CI so that your machines just end up with the final image instead of running the playbook/script on each one. Hope that helps!
For example I saw that in your blog [1] you used the base on line 1 `FROM ghcr.io/cgwalters/fedora-silverblue:37`.
I was wondering where I could find the Containerfile for that, my Google-fu and searching through the Fedora pages are failing me

That's what ends up on quay.io/fedora-ostree-desktops/ which is what we use to make our base images.
Fedora is in the middle of a transition to make more official images on quay.io/fedora, I'm sorry I don't have the info offhand, it's probably in here somewhere: https://discussion.fedoraproject.org/tag/silverblue/l/top?pe...
On the note of quay.io, is there a function on the website to see the Containerfile that created the artifact? I recall digging around in the past but couldn't really find a link to the source Containerfile.
