You’ve never heard of atomic/immutable distros? You’re part of the lucky 10,000 ;)
Bluefin, Aurora and their much more popular sister Bazzite are part of the universalBlue project: a delivery pipeline that lets anyone build their own, maintenance free atomic distro.
All uBlue projects are 100% based on Fedora Silverblue, itself an atomic distro based on Fedora. Which means that uBlue projects get automatic weekly upgrades just like Silverblue.
For people not familiar with Linux, and people who don’t want to spend any time maintaining their OS (HTPC, gaming rig etc), it’s amazing.
There are a lot of QoL improvements on uBlue projects that make them much more usable as daily drivers, like hardware accelerated codecs from rpmfusion, nvidia drivers for those who need them or actually useful preinstalled software. Plus some minor improvements on defaults.
