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.
Ah, thanks. They just set the immutability bit. Makes sense. Nice and simple, and they get to assume that nothing has changed when there are updates.
