|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following line in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "options TMPFS"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a

|
The
|
|
.Nm
|
|
driver will permit the
|
|
.Fx
|
|
kernel to access
|
|
.Tn tmpfs
|
|
file systems.
|
|
.Sh OPTIONS
|
|
The following options are available when
|
|
mounting
|
