PUFFS(4)		 BSD Kernel Interfaces Manual		      PUFFS(4)

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.
