Det kan
file kommandoen fortælle dig:
cgroup_patch: Bourne-Again shell script text executable
Du kan også bare læse første linie af scriptet for at se det. hvis du læser hele scriptet opdager du en ting mere

Som du kan se i kildekoden , altså Ja: Scriptet erstatter fuldstændigt den kerne
patch. Den gør faktisk det samme som kerne patchen ved at bruge /dev filsystemet, som er et vindue ind til kernen - det gøres ved hjælp af et bash shell script
... og det virker
Du installerer det sådan her:
Kode: Vælg alt
cd;wget http://launchpadlibrarian.net/59511828/cgroup_patch;chmod +x cgroup_patch;sudo ./cgroup_patch
For at få det til at virke, så genstarter du, eller kører:
uden at skulle genstarte
