.Dd November 22, 2009 .Dt PUFFS 4 .Os .Sh NAME .Nm puffs .Nd Pass-to-Userspace Framework File System .Sh SYNOPSIS .Cd "file-system PUFFS" .Cd "pseudo-device putter" .Sh DESCRIPTION .Nm provides a framework for creating file systems as userspace servers. The in-kernel VFS attachment is controlled through a special device node,
a /dev/puffs . People looking to implement file systems should use the system through the convenience library described in .Xr puffs 3 . .Ss Termination A .Nm file system can be unmounted regularly using .Xr umount 8 . The file system will automatically be unmounted in case the userspace server is killed or the control file descriptor closed. .Sh SEE ALSO .Xr puffs 3 .Sh HISTORY An unsupported experimental version of .Nm first appeared in .Nx 4.0 . A stable version appeared in .Nx 5.0 . .Sh AUTHORS .An Antti Kantee Aq Mt pooka@iki.fi
