rump_ntfs -- mount the ntfs file system using a userspace server
file-system PUFFS pseudo-device putter rump_ntfs [options] special node
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 sys- tem code within the kernel and therefore does not require kernel support except puffs(4). Apart from a minor speed penalty (starting from 10% and depending on the workload and file system in question), there is no dif- ference to using in-kernel code. In case mounting a file system image from a regular file, rump_ntfs does not require the use of vnconfig(8) unlike kernel file systems. Instead, the image path can be directly passed as the special file path. The exception is if the image contains a disklabel. In this case vnconfig is required to resolve the start offset for the correct partition within the image. 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 run instead of mount_ntfs(8) if ``rump'' is added to the options field of fstab(5). Please see mount_ntfs(8) for a full description of the available command line options.
