# 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.

# HISTORY

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