Wedson Almeida Filho iz Microsofta predlo\u017eio je za raspravu na mailing listi developera Linux kernela drugu verziju zakrpa sa setom omota za VFS podsustav, namijenjenih za razvoj datote\u010dnih sustava na jeziku Rust koji rade u re\u017eimu samo za \u010ditanje. Uz omote objavljena su dva voza\u010da temeljena na njima, s implementacijom datote\u010dnih sustava ext2 i tarfs, koja tako\u0111er rade u re\u017eimu samo za \u010ditanje. Za razliku od ranije dostupne implementacije FS Ext2 na jeziku Rust - ext2-rs, nova verzija radi na razini kernela (modul rust_ext2), a ne u korisni\u010dkom prostoru. Voza\u010d rust_ext2 sadr\u017ei oko 700 redaka koda na Rustu i mo\u017ee se koristiti kao polazi\u0161na to\u010dka za razvoj slo\u017eenijih implementacija FS-a, kao \u0161to je Ext4. <\/p>\n

Datote\u010dni sustav tarfs omogu\u0107uje montiranje arhiva u Tar formatu kao datote\u010dnog sustava. Voza\u010d koristi indeks vezan za tar datoteke za navigaciju kroz datoteke unutar arhiva bez potrebe za prolaskom kroz cijeli sadr\u017eaj. <\/p>\n

Odvojeno se razvija jo\u0161 jedan FS na jeziku Rust, koji koristi predlo\u017eeni sloj apstrakcija - PuzzleFS. PuzzleFS je namijenjen za smje\u0161taj izoliranih kontejnera i ima mogu\u0107nosti kao \u0161to su u\u010dinkovito pohranjivanje dupliciranih podataka, mogu\u0107nost izravnog montiranja, ponovna izrada slika, vrlo brza izrada i montiranje slika, mogu\u0107nost kori\u0161tenja neobavezne me\u0111ustupnje faze za preobrazbu (canonicalization) slika, neobaveznost potpunih prolaza kroz stablo FS-a prilikom kori\u0161tenja vi\u0161enamjenske strukture i preklapanje promjena u stilu casync.
