P\u00e5 grund af initiativet til at sikre portabiliteten af koden &#171;ZFS on Linux&#187; til andre systemer, blev der for FreeBSD <noindex><a rel=\"nofollow\" href=\"https:\/\/github.com\/zfsonfreebsd\/ZoF\">forberedes<\/a><\/noindex> tilg\u00e6ngelige pakker sysutils\/zol (v\u00e6rkt\u00f8jer) og sysutils\/zol-kmod (kernelmodul), som nu foresl\u00e5s at blive testet. I konteksten af filsystemet er den simpleste metode til testning at tilbyde f\u00e6rdige installationsbilleder, hvor den oprindelige implementering af ZFS er deaktiveret og pakkerne med &#171;ZFS on Linux&#187; er forudinstalleret. UFS og ZFS kan anvendes som filsystem til rodpartitionen.<\/p>\n<p>Lad os minde om, at udviklerne af FreeBSD i december sidste \u00e5r fremf\u00f8rte <noindex><a rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=49815\">initiativen<\/a><\/noindex> overgangen til ZFS-implementeringen fra projektet &#171;<noindex><a rel=\"nofollow\" href=\"https:\/\/zfsonlinux.org\/\">ZFS on Linux<\/a><\/noindex>&#187; (ZoL), som i den seneste tid har v\u00e6ret i fokus for al aktivitet relateret til udviklingen af ZFS. \u00c5rsagen til migrationen n\u00e6vnes som stagnationen i kodebasen for ZFS fra Illumos-projektet (en fork af OpenSolaris), som tidligere blev anvendt som grundlag for overf\u00f8relsen af ZFS-relaterede \u00e6ndringer til FreeBSD. St\u00f8tten til ZFS-kodebasen i Illumos blev hidtil h\u00e5ndteret af Delphix, som udvikler operativsystemet <noindex><a rel=\"nofollow\" href=\"https:\/\/github.com\/delphix\/delphix-os\">DelphixOS<\/a><\/noindex> (fork af Illumos). For et \u00e5r siden besluttede Delphix at skifte til &#171;ZFS on Linux&#187;, hvilket f\u00f8rte til stagnation i ZFS fra Illumos-projektet og overf\u00f8rsel af al relevante udviklingsaktivitet til &#171;ZFS on Linux&#187;, der nu betragtes som den prim\u00e6re implementering. <noindex><a rel=\"nofollow\" href=\"http:\/\/open-zfs.org\">OpenZFS<\/a><\/noindex>.<\/p>\n<p>FreeBSD-udviklerne besluttede at f\u00f8lge det generelle eksempel og ikke fors\u00f8ge at blive h\u00e6ngende i Illumos, da denne implementering allerede er meget bagud i funktionalitet og kr\u00e6ver betydelige ressourcer til vedligeholdelse af kode og overf\u00f8rsel af \u00e6ndringer. &#171;ZFS on Linux&#187; betragtes nu som det prim\u00e6re f\u00e6lles projekt til udvikling af ZFS. St\u00f8tten til FreeBSD vil blive integreret direkte i koden for &#171;ZFS on Linux&#187; og udvikles i det prim\u00e6re repository for dette projekt.<\/p>\n<p>Nogle funktioner, der er
