RUMP_EXT2FS(8)		  BSD System Manager's Manual		RUMP_EXT2FS(8)

NAME
     rump_ext2fs — mount a ext2fs image with a userspace server

SYNOPSIS
     file-system PUFFS
     pseudo-device putter

     rump_ext2fs [options] image mountpoint

DESCRIPTION
     NOTE! This manual page describes features specific to the rump(3) file
     server.  Please see mount_ext2fs(8) for a full description of the avail‐
     able command line options.

     The rump_ext2fs utility can be used to mount ext2fs file systems.	It
     uses rump(3) and p2k(3) to facilitate running the file system as a server
     in userspace.  As opposed to mount_ext2fs(8), rump_ext2fs 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_ext2fs 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_ext2fs instead of mount_ext2fs(8).  Corrupt file system images com‐
     monly cause the file system to crash the entire kernel, but with
     rump_ext2fs only the userspace server process will dump core.

     To use rump_ext2fs via mount(8), the flags -o rump and -t ext2fs should
     be given.	Similarly, rump_ext2fs is used instead of mount_ext2fs(8) if
     “rump” is added to the options field of fstab(5).

HISTORY
     The rump_ext2fs utility first appeared in NetBSD 5.0.
