.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 .
