A cgroup holding processes cannot enable controllers for its children, so init/ had to stay a leaf. The hotplug helpers 10-hotplug.conf.in places there ended up in groups where cpu.weight and friends could never be set. Keeping PID 1 in the root cgroup makes init/ a domain like the others. It also unbreaks lxc-based runtimes: liblxc bases the container tree on PID 1's cgroup and only special-cases systemd's init.scope/, so under Finit it landed containers in init/, with no controllers available.

Finit is a fast, simple alternative to SysV init and systemd, designed for small and embedded Linux systems. It can also run on desktop and server systems, like finix.

- 🛠️ Buildroot embedded Linux,
- 📦 Debian GNU/Linux,
- ⛰️ Alpine Linux, and
- 🌌 Void Linux
Note
Finit can run on various Linux distributions, but the bundled install scripts are examples only. They have been tested on amd64 (x86_64) systems with standard configurations.
For embedded systems, see these Buildroot-based examples: myLinux, Infix, or br2-finit-demo.
