The rump_ntfs utility can be used to mount
    ntfs file systems. It uses
    rump(3) and
    p2k(3) to facilitate running the
    file system as a server in userspace. As opposed to
    mount_ntfs(8),
    rump_ntfs does not use file system code within the
    kernel and therefore does not require kernel support except
    puffs(4). Apart from a minor
    speed penalty there is no downside with respect to in-kernel code.
rump_ntfs does not require using
    vnconfig(8) for mounts from
    regular files and the file path can be passed directly as the
    image parameter. In fact, the use of
    vnconfig(8) is discouraged,
    since it is unable to properly deal with images on sparse files.
In case the image contains multiple partitions, the desired partition must be indicated by appending the token “%DISKLABEL:p%” to the image path. The letter “p” specifies the partition as obtained via disklabel(8). For example, to mount partition “e” from image /tmp/wd0.img, use “/tmp/wd0.img%DISKLABEL:e%”.
It is recommended that untrusted file system images be mounted
    with rump_ntfs instead of
    mount_ntfs(8). Corrupt
    file system images commonly cause the file system to crash the entire
    kernel, but with rump_ntfs only the userspace server
    process will dump core.
To use rump_ntfs via
    mount(8), the flags
    -o rump and
    -t ntfs should be given.
    Similarly, rump_ntfs is used instead of
    mount_ntfs(8) if
    “rump” is added to the options field of
    fstab(5).
rump_ntfs utility first appeared in
  NetBSD 5.0.
