Usage

JSR-203 & fuse

    URI uri = URI.create("jnode:file:/foo/bar.nhd");
    fs = FileSystems.newFileSystem(uri, Collections.emptyList());
    Fuse fuse = Fuse.getFuse().mount(fs, MOUNT_POINT, Collections.emptyList());

for emulator user

it's possible to mount old school japanese computer pc-9801's virtual disk by fuse.
we can see nostalgic files autoexec.bat, command.com, mifes... etc.
time stamps are so old lol.

TODO

• BlockDeviceAPI can only support [header] + solid image
  • api separation from device is in high esteem
  • however we need accessing disk data by logical sector No. but offset like BiosDeviceAPI for emu disks like d88 ... resolved by ad-hoc way
