Po zaraden\u00ed opr\u00e1v do hlavn\u00e9ho jadra Linuxu sa spolo\u010dnos\u0165 Paragon Software pl\u00e1nuje postara\u0165 o udr\u017eiavanie, opravu ch\u00fdb a roz\u0161\u00edrenie funk\u010dnosti.<\/p>\n

Napriek tomu m\u00f4\u017ee by\u0165 zaradenie do jadra \u010dasovo n\u00e1ro\u010dn\u00e9 kv\u00f4li potrebe presk\u00famania navrhnut\u00e9ho k\u00f3du extern\u00fdmi v\u00fdvoj\u00e1rmi.

Takisto sa zd\u00f4raz\u0148uje potreba s\u00fahlasu s pridan\u00edm novej implement\u00e1cie NTFS pri existencii star\u00e9ho ovl\u00e1da\u010da fs\/ntfs, ktor\u00fd pracuje v re\u017eime iba na \u010d\u00edtanie.<\/p>\n

Predt\u00fdm bolo pre pln\u00fd pr\u00edstup k NTFS oddielom z Linuxu potrebn\u00e9 pou\u017e\u00edva\u0165 FUSE ovl\u00e1da\u010d NTFS-3g, ktor\u00fd pracoval v u\u017e\u00edvate\u013eskom priestore a nezabezpe\u010doval po\u017eadovan\u00fa v\u00fdkonnos\u0165.

Prv\u00e1 verzia ovl\u00e1da\u010da bola obmedzen\u00e1 na pr\u00e1cu iba v re\u017eime \u010d\u00edtania, ale vo v\u00fdvoji bola verzia s podporou z\u00e1pisu. Tieto patche ostali nevyu\u017eit\u00e9 a do hlavn\u00e9ho jadra bol prijat\u00fd ovl\u00e1da\u010d exFAT, navrhnut\u00fd<\/a><\/noindex> Samsung a pou\u017e\u00edvan\u00fd vo firmv\u00e9ri smartf\u00f3nov Android tejto spolo\u010dnosti.
