pl-srv

pl-srv or the PortaLinux Init System package is a very tiny init system made specifically for the PortaLinux operating system. It is written in C99 using POSIX calls and the ESB/PortaLinux API. The only component with Linux-specific system calls is pl-init and it's only used to shut down/restart the system.

It is heavily inspired by systemd-init, but it cuts out a lot of the fat.

Components

The pl-srv init system package consists of the following components:

• libsrv: A library containing most of the functionality of the pl-srv and pl-init programs. It is entirely written using POSIX and ESB/PL-API calls, and thus is completely portable and can be compiled and ran on any operating system that fully implements the POSIX.1-2008 API.

• pl-init: A minimal PID 1 program meant to have as little functionality as possible. Its main purpose is to make the system not crash, even if everything else does. It only starts up the pl-srv service supervisor in init mode and then gets into a forever loop that gets rid of zombie processes. This is the only Linux-specific component of the pl-srv package

• pl-srv: A simple service supervisor with a small footprint. This is the main program of this package. It only makes calls to libsrv, which means it is portable and can run on anything libsrv runs on.

Contributions

I do plan on accepting contributions to the project once it gets to its 1.0 release, but currently, no contributions are being accepted.
