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...
Mõiste
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.

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
