Pass-to-Userspace Framework File System
file-system PUFFS
pseudo-device putter
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).
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.
An unsupported experimental version of
puffs
first appeared in NetBSD
4.0. A stable version appeared in NetBSD
5.0.
