Writing Device Drivers

Optionally Editing /etc/devlink.tab

If the driver creates minor nodes that do not represent disks, tapes, or ports (terminal devices), /etc/devlink.tab can be modified to cause devlinks(1M) to create logical device names in /dev. See devlink.tab(4) for a description of the syntax of this file.

Alternatively, logical names can be created by a program run at driver installation time.
