I have one question: what do you mean when write, that this software is intended to use with ZFS? Could it be used to provide access to raw (disk) devices? Is it safe? Ok, it can have bugs, but is it as safe as access to file placed on ZFS (you test it in such configuration, am I right?)? --=20 // Black Lion AKA Lev Serebryakov
