Tag File System:

Først holdes en tabel over tags.
Her findes det tag man ønsker, som holder en pointer til tabellen med de filer der er for det tag.
I denne fil holdes en pointer til selvefilen, herudover holdes der også information om, om der må læses
eller skrives til denne fil.
Det kunne give mening at have "Service" som et tag, filer liggende i dette tag er dem der starter med systemet.
På den måde er det nemt at få overblik over hvilke service der startes med computeren.
