The rules for device naming are read from the files located in the
.B ID
Match the device number on the bus, like PCI bus id.
.TP
-.B PLACE
-Match the topological position on bus, like physical port of USB device
-.TP
.BI SYSFS{ filename }
Match sysfs device attribute like label, vendor, USB serial number, SCSI UUID
or file system label. Up to 5 different sysfs files can be checked, with
.B NAME
The name of the node to be created, or the name, the network interface
should be renamed to.
-.br
-If given with the attribute
-.BR NAME{ all_partitions }
-.B udev
-will create device nodes for all 15 partitions of a blockdevice.
-This may be useful for removable media devices.
-.br
-If given with the attribute
-.BR NAME{ ignore_remove }
-.B udev
-will ignore any later remove event for this device.
-This may be useful as a workaround for broken device drivers.
-.sp
-Multiple attributes may be separated by comma.
.TP
.B SYMLINK
The name of a symlink targeting the node. Multiple symlinks may be

.B OWNER, GROUP, MODE
The permissions for the device node. Every specified value overwrites the

+.B ignore_device

+.B ignore_remove

.RB "The " NAME ", " SYMLINK ", " PROGRAM ", " OWNER " and " GROUP
fields support simple printf-like string substitutions:
.B %k
The "kernel name" for the device.
.TP
+.B %p
+The devpath for the device.
+.TP
.B %M
The kernel major number for the device.
.TP
all remaining parts of the result string are substituted:
.BI %c{ N+ }
.TP

+The name of a created temporary device node to provide access to the

The content of a sysfs attribute.
