Wedson Almeida Filho z Microsoftu navrhol na diskusiu v mailingliste v\u00fdvoj\u00e1rov Linuxov\u00e9ho jadra druh\u00fa verziu patchov so s\u00faborom rozhran\u00ed nad subsyst\u00e9mom VFS, ur\u010den\u00fdch na v\u00fdvoj s\u00faborov\u00fdch syst\u00e9mov v jazyku Rust, ktor\u00e9 funguj\u00fa v re\u017eime len na \u010d\u00edtanie. Spolu s rozhraniami boli zverejnen\u00e9 dva ovl\u00e1da\u010de s implement\u00e1ciou s\u00faborov\u00fdch syst\u00e9mov ext2 a tarfs, pracuj\u00facich v re\u017eime len na \u010d\u00edtanie. Na rozdiel od predt\u00fdm dostupnej implement\u00e1cie FS Ext2 v jazyku Rust - ext2-rs, nov\u00fd variant funguje na \u00farovni jadra (modul rust_ext2), a nie v u\u017e\u00edvate\u013eskom priestore. Ovl\u00e1da\u010d rust_ext2 obsahuje pribli\u017ene 700 riadkov k\u00f3du v Rust a m\u00f4\u017ee by\u0165 pou\u017eit\u00fd ako v\u00fdchoz\u00ed bod pre v\u00fdvoj zlo\u017eitej\u0161\u00edch implement\u00e1ci\u00ed FS, ako je Ext4. <\/p>\n

Samostatne sa vyv\u00edja \u010fal\u0161\u00ed FS v jazyku Rust, ktor\u00fd vyu\u017e\u00edva navrhnut\u00fd abstrahovan\u00fd vrstven\u00fd syst\u00e9m - PuzzleFS.
