.Nd "efficient memory file system"
|
|
.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
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
tmpfs_load="YES"
|
|
.Ed

|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver will permit the
|
|
.Fx
|
|
kernel to access
|
|
.Tn tmpfs
|
|
file systems.
|
|
.Sh EXAMPLES
|
|
To mount a
|
|
.Nm
|

The
|
|
.Nm
|
|
kernel implementation was written by
|
|
.An Julio M. Merino Vidal Aq jmmv@NetBSD.org
|
|
as a Google SoC project.
|
|
.Pp
|
|
.An Rohit Jalan
|

|
.Sh BUGS
|
|
The
|
|
.Nm
|
|
kernel implementation is currently considered as
