Sissejuhatus
Antud artiklis ma ... Milleks see on vajalik ja kasulik on.. Jagasin kaheks osaks. Esimeses osas hakkan rohkem räägima teooriast: mõistetest... Teises osas juba liikun praktika...
Teorootiline osa
Üldine ülevaate
Init (ehk initialization) on rakendus mõelnud UNIX süsteemidele mis käivitab kõike teiste protsessi. Igal UNIX operatsioonsüsteemis init konfig on natukene teistsugune, aga üldiselt võib öelda, et tegu on runlevel-itega. Igal runlevel-il on oma PID, ehk number mis vastutab kuidas käivitatakse operatsioonsüsteemi.
Erinevates Linuxi derivatiivides on sisseehitatud oma rakendus, kuidas init-i funktsioonlsust rakendatatakse. Enamus Linuxi distrod kasutavad System V. Ubuntul on selle jaoks mõelnud Upstart.

Init alternatiivid
Various efforts have been made to replace the traditional init daemons with something better. Below is a list of these alternatives in no particular order.
SystemStarter
a process spawner started by the BSD-style init in Mac OS X prior to Mac OS X v10.4
launchd
a replacement for init introduced in Mac OS X v10.4 (it launches SystemStarter to run old-style 'rc.local' and SystemStarter processes)
Initng
a full replacement of init designed to start processes asynchronously
Upstart
a full replacement of init designed to start processes asynchronously initiated by Ubuntu
=== Service Management Facility === a complete full replacement/redesign of init from the ground up in Solaris starting with Solaris 10
runit
a cross-platform full replacement for init with parallel starting of services
BootScripts
in GoboLinux
DEMONS
a modification of the init start process by KahelOS, where daemons are started only when the DE (desktop environment) started.
Mudur
an init replacement written in Python and designed to start process asynchronously in use by the Pardus Linux distribution.
Vähem tuntud alternatiivid
Siin on alltootud veel igasuguseid init... Kui tunnete huvi vastu, võite uurida...
eINIT, a full replacement of init designed to start processes asynchronously, but with the potential of doing it without shell-scripts svscan from daemontools used as process 1 - seems to be superseded by runit cinit twsinit, partly written in x86 assembler, more a proof of concept minit ninit OpenRC systemd, a replacement for init with parallel starting of services, initiated by Red Hat.
Init-i rakendamine praktikas
