Nitrux uses OpenRC instead of systemd, unlike most mainstream distros. It also features the Liquorix kernel, described as “an enthusiast Linux kernel designed for uncompromised responsiveness in interactive systems, enabling low latency in A/V production, and reduced frame time deviations in games.”
New in this release is kboot, a utility to switch kernels on-the-fly without needing a reboot, and VMetal, which allows users to run Windows in parallel to Nitrux to provide users of access to Windows software.
Huh, it’s the anti-Fedora Silverblue; swapping out Systemd, Flatpaks and Gnome. Absolutely has it’s place, even if I’ll never use it. Fedora has made some pretty amazing software over the years.
No mention anywhere about how the immutability is manged.
There’s some info here on the immutability: https://nxos.org/tutorial/filesystem-security-privacy-and-anonymization-features-in-nitrux/#xfs-features-and-root-immutability-in-nitrux
