In\u017einieri z firmy Google zverejnili pre v\u00fdvoj\u00e1rov jadra Linux s\u00fabor patchov s implement\u00e1ciou subsyst\u00e9mu Live Update Orchestrator (LUO), ur\u010den\u00e9ho na aktualiz\u00e1ciu jadra v re\u00e1lnom \u010dase. Na rozdiel od tak\u00fdch mechanizmov, ako s\u00fa livepatch, Ksplice, kpatch a kGraft, nov\u00fd syst\u00e9m nie je obmedzen\u00fd len na aplik\u00e1ciu jednotliv\u00fdch opr\u00e1v na be\u017eiace jadro Linux, ale umo\u017e\u0148uje \u00faplne re\u0161tartova\u0165 a aktualizova\u0165 jadro bez zastavenia chodu jednotliv\u00fdch zariaden\u00ed.

Na koordin\u00e1ciu uchov\u00e1vania stavu a prep\u00ednania na nov\u00e9 jadro LUO poskytuje API, ktor\u00e9 umo\u017e\u0148uje \u010fal\u0161\u00edm subsyst\u00e9mom jadra pripoji\u0165 spracovate\u013eov na sledovanie a \u00fa\u010das\u0165 v procese Live-re\u0161tartu.
