NAME

     puffs -- Pass-to-Userspace Framework File System

SYNOPSIS

     file-system PUFFS
     pseudo-device putter

DESCRIPTION

     puffs provides a framework for creating file systems as userspace servers.  The in-kernel VFS attachment is controlled through a special
     device node, /dev/puffs.  People looking to implement file systems should use the system through the convenience library described in
     puffs(3).

   Termination
     A puffs file system can be unmounted regularly using umount(8).  The file system will automatically be unmounted in case the userspace server
     is killed or the control file descriptor closed.

SEE ALSO

     puffs(3)

HISTORY

     An unsupported experimental version of puffs first appeared in NetBSD 4.0.  A stable version appeared in NetBSD 5.0.

RUMP_TMPFS(8)						    BSD 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).

HISTORY

     The rump_tmpfs utility first appeared in NetBSD 5.0.
