.Sh DESCRIPTION
The
.Nm
driver is the kernel component of the automounter infrastructure.
Its job is to pass mount requests to the
.Xr automountd 8
daemon, and pause the processes trying to access the automounted filesystem
until the mount is completed.
It is mounted by the
.Xr automount 8 .

.Bl -tag -width indent

Mount options for all filesystems specified in the map entry.
.It Cm master_prefix
Filesystem mountpoint prefix.
.El
.Sh EXAMPLES
To unmount all mounted
.Nm
filesystems:
.Pp
.Dl "umount -At autofs"
.Pp

.Sh HISTORY
The
.Nm
driver first appeared in
.Fx 10.1 .
The
.Nm
driver first appeared in
.Dx 4.5 .
.Sh AUTHORS
The
.Nm
was developed by
.An Edward Tomasz Napierala Aq Mt trasz@FreeBSD.org
under sponsorship from the FreeBSD Foundation.
.Pp
The
.Nm
was ported to
.Dx
by
.An Tomohiro Kusumi Aq Mt tkusumi@netbsd.org .

.Sh BUGS
The
.Nm
driver on
.Dx
currently does't support
.Pa vfs.autofs.mount_on_stat
sysctl.
This sysctl is disabled by default on both
.Fx
and
.Dx ,
but enabling it does nothing on
.Dx .
