.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
file provides an easy way to set ownership and permissions, or create
|
|
links for devices available at boot.
|
|
.Pp
|
|
It does not work for devices plugged in and out after the system is up
|
|
and running, e.g.\& USB devices.
|
|
See
|
|
.Xr devfs.rules 5
|
|
for setting ownership and permissions for all device nodes, and
|
|
.Xr devd.conf 5
|
|
for actions to be taken when devices are attached or detached.
|
|
.Pp

|
Lines starting with a hash sign
|
|
.Pq Ql #
|
|
and empty lines are ignored.
|
|
The lines that specify

|
rules consist of three parameters separated by whitespace:
|
|
.Bl -tag -width indent
|
|
.It Ar action
|
|
The action to take for the device.
|
|
The action names are only significant to the first unique character.

.Xr devfs 5 .
|
|
.It Ar arg
|
|
The argument of the

|
.El
|
|
.Pp
|
|
The actions currently supported are:
|
|
.Bl -tag -width indent
|
|
.It Ic link
|
|
This action creates a symbolic link named
|
|
.Ar arg
|
|
that points to
|
|
.Ar devname ,
|
|
the name of the device created by
|
|
.Xr devfs 5 .
|
|
.It Ic own
|
|
This action changes the ownership of
|
|
.Ar devname .
|
|
The
|
|
.Ar arg
|
|
parameter must be in the form of an
|
|
.Ar owner Ns : Ns Ar group
|
|
pair, in the same format used by
|
|
.Xr chown 8 .
|
|
.It Ic perm
|
|
This action changes the permissions of
|
|
.Ar devname .
|
|
The

|
|
.Bd -literal -offset indent
|
|
link cd0 cdrom
|
|
.Ed
|
|
.Pp
|
|
To set the owner of a device, the

|
|
own cd0 root:cdrom
