.Sh DESCRIPTION
.Nm
is a reimplementation of the file system in user space subsystem.
Operations are transported from the kernel virtual file system layer
to the concrete implementation behind
.Nm ,
where they are processed and results are sent back to the kernel.
.Pp
It uses the framework provided by the
.Xr puffs 3
subsystem, and, through that, the kernel interface provided by
.Xr puffs 4 .
.Sh SEE ALSO
.Xr puffs 3 ,
.Xr puffs 4
.Sh HISTORY
An unsupported experimental version of
.Nm
first appeared in
.Nx 5.0 .
