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. AUTHORS

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
