|

|
||||||

|

.Sh DESCRIPTION
|
||||||
|
The
|
||||||
|
.Nm vnconfig
|
||||||
|
command configures and enables vnode pseudo disk devices.
|
||||||
|
The first form of the command will associate the special file
|
||||||
|
.Ar special_file
|
||||||
|
with the regular file
|
||||||
|
.Ar regular_file
|
||||||
|
allowing the latter to be accessed as though it were a disk.
|
||||||
|
Hence a regular file within the filesystem can be used for swapping
|
||||||
|
or can contain a filesystem that is mounted in the name space.
|
||||||
|
.Pp
|
||||||
|
Options indicate an action to be performed:
|
||||||
|
.Bl -tag -width indent
|
||||||
|
.It Fl c
|
||||||
|
Configures the device.
|
||||||
|
If successful, references to
|
||||||
|
.Ar special_file
|
||||||
|
will access the contents of
|
||||||
|
.Ar regular_file .
|
||||||
|
.It Fl e
|
||||||
|
Configures the device and enables any
|
||||||
|
.Ar feature
|
||||||
|
that was specified.
|
||||||
|
If no feature was specified,
|
||||||
|
.Fl e
|
||||||
|
is the same as
|
||||||
|
.Fl c .
|
||||||
|
.It Fl d
|
||||||
|
Disables (if possible) the specified feature.
|
||||||
|
.It Fl u
|
||||||
|
Disables and ``unconfigures'' the device.
|
||||||
|
.It Fl v
|
||||||
|
Print messages to stdout describing actions taken.
|
||||||
|
.El
|
||||||
|
.Pp
|
||||||
|
If no action option is given,
|
||||||
|
.Fl c
|
||||||
|
is assumed.
|
||||||
|
.Pp
|
||||||
|
The
|
||||||
|
.Ar feature
|
||||||
|
argument specifies a feature that can be enabled via the
|
||||||
|
.Fl e
|
||||||
|
option:
|
||||||
|
.Bl -tag -width indent
|
||||||
|
.It Dv swap
|
||||||
|
Swapping is enabled on the special file.
|
||||||
|
See
|
||||||
|
.Xr swapon 2 .
|
||||||
|
.It Dv Pf mountro= Pa mount_point
|
||||||
|
The special file is mounted read-only on
|
||||||
|
.Ar mount_point .
|
||||||
|
See
|
||||||
|
.Xr mount 2 .
|
||||||
|
.It Dv Pf mountrw= Pa mount_point
|
||||||
|
The special file is mounted read-write on
|
||||||
|
.Ar mount_point .
|
||||||
|
See
|
||||||
|
.Xr mount 2 .
|
||||||
|
.It Dv Pf mount= Pa mount_point
|
||||||
|
Same as ``mountrw=''.
|
||||||
|
.El
|
||||||
|
.Pp
|
||||||
|
The second (-a) form of the command reads a command file and performs the
|
||||||
|
specified actions for each device/file pair.
|
||||||
|
With
|
||||||
|
.Fl f
|
||||||
|
it reads the indicated configuration file
|
||||||
|
.Ar config_file .
|
||||||
|
Otherwise it uses a default configuration file.
|
||||||
|
A configuration file contains one line per device/file pair in the form:
|
||||||
|
.Bd -literal
|
||||||
|
special_file regular_file [ feature ]
|
||||||
|
.Ed
|
||||||
|
.Pp
|
||||||
|
where fields are seperated by white space.
|
||||||
|
The previously described action options serve to configure, enable,
|
||||||
|
disable or unconfigure all devices in the configuration file.
|
||||||
|
.Sh FILES
|
||||||
|
.Bl -tag -width /etc/vntab -compact
|
||||||
|
.It Pa /etc/vntab
|
||||||
|
default configuration file for
|
||||||
|
.Fl a
|
||||||
|
option.
|
||||||
|
.El
|
||||||
|
.Sh EXAMPLES
|
||||||
|
.Pp
|
||||||
|
.Dl vnconfig /dev/vn0c /tmp/diskimage
|
||||||
|
.Pp
|
||||||
|
Configures the vnode disk
|
||||||
|
.Pa vn0c .

||||||
|
.Pp
|
||||||
|
.Dl vnconfig -e /dev/vn0c /var/swapfile swap
