Wedson Almeida Filho de la Microsoft a propus pentru discu\u021bie \u00een lista de coresponden\u021b\u0103 a dezvoltatorilor kernel-ului Linux a doua versiune a patch-urilor cu un set de wrapperi peste subsistemul VFS, destinat dezvolt\u0103rii de sisteme de fi\u0219iere \u00een limbajul Rust, care func\u021bioneaz\u0103 \u00een mod doar pentru citire. \u00cempreun\u0103 cu wrapperii, au fost publicate dou\u0103 drivere create pe baza acestora care implementeaz\u0103 sisteme de fi\u0219iere ext2 \u0219i tarfs, func\u021bion\u00e2nd \u00een mod doar pentru citire. Spre deosebire de implementarea anterioar\u0103 a FS Ext2 \u00een lemnajul Rust - ext2-rs, noua variant\u0103 func\u021bioneaz\u0103 la nivel de kernel (modul rust_ext2), \u0219i nu \u00een spa\u021biul utilizatorului. Driverul rust_ext2 con\u021bine aproximativ 700 de linii de cod \u00een Rust \u0219i poate fi folosit ca punct de plecare pentru dezvoltarea unor implement\u0103ri mai complexe de FS, cum ar fi Ext4. <\/p>\n

Sistemul de fi\u0219iere tarfs permite montarea arhivelor \u00een format Tar ca un sistem de fi\u0219iere. Driverul folose\u0219te un index ata\u0219at la fi\u0219ierele tar pentru a naviga prin fi\u0219ierele din interiorul arhivei f\u0103r\u0103 a parcurge \u00eentregul con\u021binut. <\/p>\n

Separat, se dezvolt\u0103 o alt\u0103 FS \u00een limbajul Rust, care utilizeaz\u0103 stratul de abstrac\u021bie propus - PuzzleFS. PuzzleFS este destinat pentru plasarea containerelor izolate \u0219i are capacit\u0103\u021bi precum stocarea eficient\u0103 a datelor duplicat, posibilitatea de montare direct\u0103, reconstruirea repetat\u0103 a imaginilor, construire \u0219i montare de imagini foarte rapide, posibilitatea de a utiliza o etap\u0103 intermediar\u0103 op\u021bional\u0103 pentru transformarea (canonizarea) imaginilor, necesitatea op\u021bionalit\u0103\u021bii a parcurgerii complete a arborelui FS atunci c\u00e2nd se folose\u0219te o structur\u0103 stratificat\u0103 \u0219i suprapunerea modific\u0103rilor \u00een stil casync.
