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.
