The Epoch Init System: A New Beginning.
Single or multiple configuration file setup, your choice.
Tracks processes with high accuracy, and supports PID files, PIDs, and commands as a method for stopping a service.
Uses numeric priority groups to determine startup order of services.
Simple, easy-to-follow, single threaded non-parallel design.
Can automatically restart dead services.
Supports user/group setting, working directory setting, environment variable setting, stderr/stdout redirection, and more.
Includes implementations of killall5 and wall, neither of which are mandatory.
All applets are symlinks to the central binary.
Power control functions restricted to users in the wheel/root group. (group zero).
Extensive service status and control commands for system administration.
Can kill stuck boot and shutdown jobs and continue booting or shutting down via CTRL-ALT-DEL.
Uses a simple custom IPC for applet communication with init.
And much more!
The Epoch Init System is a small but powerful init system for Linux 2.6+.
It requires a libc, (not glibc specific), a Linux kernel of 2.6 or greater,
a shell is recommended, and while it will function somewhat without it, /proc.
It has very low memory usage, very small binary size, and is designed to be suitable
for both full blown desktop and server systems as well as keeping minimalist and embedded
distros heavily in mind. It is architecture and compiler independent, written in mostly ANSI C,
and is designed with a philosophy in mind:
1. Features that aren't our business aren't our business.
2. Service tracking and management is the business of the init system
3. Be unintrusive and easily replaced without a reinstall of the OS.
4. Don't require any dependency libraries outside of libc.
5. Be small and efficient, but not so small as to be a poor choice for desktops and servers.
6. Be easily configured and tidy with our configuration.
7. If it's easy as well as non-costly to implement, and people wish they could do that, let them do that.
The last pillar has resulted in some interesting and useful options that I'm sure many can appreciate.
