s6 Alternatives

    s6 is described as 'small suite of programs for UNIX, designed for process supervision. It can be used as an init system. You can also use all its programs separately' and is an app in the OS & Utilities category. There are eight alternatives to s6 for a variety of platforms, including Linux, BSD, Mac, PC-BSD and FreeBSD. The best alternative is systemd, which is both free and Open Source. Other great apps like s6 are sysvinit (Free, Open Source), OpenRC (Free, Open Source), runit (Free, Open Source) and nosh (Free).

    1. systemd is a replacement for the init daemon for Linux (either System V or BSD-style). It is intended to provide a better framework for expressing services' dependencies, allow more work to be done concurrently at system startup, and to reduce shell overhead.

      burnx50 systemd is not portable, is not truly modular and is not small code-wise.

      runit is a cross-platform Unix init scheme with service supervision, a replacement for sysvinit, and other init schemes. It runs on GNU/Linux, *BSD, MacOSX, Solaris, and can easily be adapted to other Unix operating systems.

      Finit is a small SysV init replacement with process supervision similar to that of daemontools and runit. Its focus is on small and embedded GNU/Linux systems, although fully functional on standard server and desktop installations.

      Using the tooling in this repo, I am able to boot from linux to sinit as PID1, and from there to Emacs acting as PID2 using --script mode, performing all typical rc.boot system initialization using Emacs lisp until we hit the getty.
