NetBSD 6.1.5 - man page for rump_ntfs (netbsd section 8)

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

     rump_ntfs -- mount a ntfs image with a userspace server

     file-system PUFFS
     pseudo-device putter

     rump_ntfs [options] image mountpoint

     NOTE! This manual page describes features specific to the rump(3) file server.  Please see
     mount_ntfs(8) for a full description of the available 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 discour-
     aged, 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

     p2k(3), puffs(3), rump(3), mount_ntfs(8)

     The rump_ntfs utility first appeared in NetBSD 5.0.
