cinit - Daemons backgrounding
|
|
=============================
|
|
Nico Schottelius <nico-cinit==@==schottelius.org>
|
|
0.1, for cinit 0.3, Initial versinon from 2005-06-12
|
|
|
|
|
|
This document describes the backgrounding process and how to disable it.
|
|
|
|
|
|
|
|
Definition
|
|
-----------
|
|
A daemon is a program which runs in the background.
|
|
Running in the background means you cannot access the process
|
|
directly (like you can press a key in a shell).
|
|
|
|
|
|
Daemons and cinit
|
|
------------------
|
|
cinit normally watches system services and restarts them
|
|
(`respawn` flag in the configuration). If the process goes to background,
|
|
cinit cannot control it directly anymore.
|
|
|
|
