NSpawn Subsystem for Linux (nsl) v0.4.0 is out, allowing developers to run multiple Linux machines on a single host, akin to WSL for Windows. Each machine is a full distro with its own packages and services, running as a systemd-nspawn container in a small VM. This is a big deal for developers who need isolation and flexibility in their workflows, as nsl provides a sandboxed environment without altering host files or permissions. Seven signed distros are available, including Debian, Ubuntu, Fedora, and more, rebuilt weekly and verified against the Frostyard publishing workflow. The first release, v0.4.0, is tested on Snow Linux 13 with specific versions of QEMU, virtiofsd, and GNOME Wayland.
Key Points
NSpawn Subsystem for Linux v0.4.0 allows running multiple Linux machines on a single host, similar to WSL for Windows.
