RUMP_TMPFS(8)               System Manager's Manual              RUMP_TMPFS(8)

NAME
     rump_tmpfs -- mount a tmpfs fictional fs with a userspace server

SYNOPSIS
     file-system PUFFS
     pseudo-device putter

     rump_tmpfs [options] tmpfs mountpoint

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

     The rump_tmpfs utility can be used to mount tmpfs file systems.  It uses
     rump(3) and p2k(3) to facilitate running the file system as a server in
     userspace.  As opposed to mount_tmpfs(8), rump_tmpfs 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.

     To use rump_tmpfs via mount(8), the flags -o rump and -t tmpfs should be
     given.  Similarly, rump_tmpfs is used instead of mount_tmpfs(8) if
     ``rump'' is added to the options field of fstab(5).

SEE ALSO
     p2k(3), puffs(3), rump(3), mount_tmpfs(8)

HISTORY
     The rump_tmpfs utility first appeared in NetBSD 5.0.
