RUMP_NTFS(8)						    BSD System Manager's Manual 					      RUMP_NTFS(8)

NAME
     rump_ntfs -- mount a ntfs image with a userspace server

SYNOPSIS
     file-system PUFFS
     pseudo-device putter

     rump_ntfs [options] image mountpoint

DESCRIPTION
     NOTE! This manual page describes features specific to the rump(3) file server.  Please see mount_ntfs(8) for a full description of the avail-
     able command line options.

     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).
