Alexander Larsson, krijuesi i Flatpak dhe punonj\u00ebs n\u00eb Red Hat, prezantoi nj\u00eb version paraprak t\u00eb patch-ave me implementimin e sistemit t\u00eb skedar\u00ebve Composefs p\u00ebr kernelin Linux. Sistema e skedar\u00ebve e propozuar ngjan me Squashfs dhe \u00ebsht\u00eb gjithashtu e p\u00ebrshtatshme p\u00ebr montimin e imazheve n\u00eb modin vet\u00ebm p\u00ebr lexim. Dallimet p\u00ebrqendrohen n\u00eb sigurin\u00eb e ndarjes s\u00eb efikasitetit t\u00eb p\u00ebrmbajtjes s\u00eb disa imazheve t\u00eb diskut t\u00eb montuar dhe mb\u00ebshtetje p\u00ebr verifikimin e t\u00eb dh\u00ebnave t\u00eb lexueshme. Si zona p\u00ebrdorimi ku mund t\u00eb k\u00ebrkohet FS Composefs p\u00ebrmendet montimi i imazheve t\u00eb kontejner\u00ebve dhe p\u00ebrdorimi p\u00ebr nj\u00eb arkiv t\u00eb ngjash\u00ebm me Git, OSTree. <\/p>\n
N\u00eb Composefs aplikohet nj\u00eb model ruajtjeje me adresim t\u00eb bazuar n\u00eb p\u00ebrmbajtje, dmth identifikuesi primar nuk \u00ebsht\u00eb emri i skedarit, por nj\u00eb hash i p\u00ebrmbajtjes s\u00eb skedarit. Ky model siguron deduplikimin dhe lejon q\u00eb n\u00eb fakt t\u00eb ruhet vet\u00ebm nj\u00eb kopje e skedar\u00ebve identik\u00eb q\u00eb gjenden n\u00eb ndarjet e ndryshme t\u00eb montuara. P\u00ebr shembull, imazhet e kontejner\u00ebve p\u00ebrmbajn\u00eb shum\u00eb skedar\u00eb sistematik\u00eb typik\u00eb dhe n\u00eb rastin e p\u00ebrdorimit t\u00eb Composefs \u00e7do skedar i till\u00eb do t\u00eb aksesohet nga t\u00eb gjitha imazhet e montuara, pa p\u00ebrdorur truke si\u00e7 jan\u00eb lidhjet e forta. K\u00ebshtu, skedar\u00ebt e p\u00ebrbashk\u00ebt jo vet\u00ebm q\u00eb ruhet si nj\u00eb kopje n\u00eb disk, por gjithashtu menaxhohen me nj\u00eb sh\u00ebnim n\u00eb caches, duke ofruar mund\u00ebsin\u00eb p\u00ebr t\u00eb kursyer si hap\u00ebsir\u00eb n\u00eb disk ashtu edhe memorie RAM. <\/p>\n
