Dotaz: hd-idle a child procesy? init script

[Lucius]

Ahoj, chtel bych poradit, kdyz resim init script pro hd-idle pres sysV template https://github.com/jasonblewis/sample-service-script/blob/master/service.sh Jenze to vypada, ze si hd-idle pri spusteni forkne proces a puvodni zabije a cislo procesu pak neodpovida pri stopovani napr. Muzete mi poradit, jak tohle osetrit, diky?

Čo je to za distribúcie? Nebolo by jednoduchšie urobiť presne to, čo robí hd-idle v init skripte?

Debian, čisté LSB a aj iné distribúcie majú funkciu, ktorá sa používa v init skriptoch a ktorá funguje aj bez pid (funguje to tak, žesa hľadá bežiaci proces zodpovedajúci spustiteľnému súboru).
