That's device name (with regex match), uid:gid, and permissions.
- Optionally, that can be followed (on the same line) by an asterisk
- and a command line to run after creating the corresponding device(s),
- ala:
-
- hdc root:cdrom 660 *ln -s hdc cdrom
-
Config file parsing stops on the first matching line. If no config
entry is matched, devices are created with default 0:0 660. (Make
the last line match .* to override this.)

+ depends on CONFIG_FEATURE_MDEV_CONF
+ help
+ This adds support for an optional field to /etc/mdev.conf, consisting
+ of a special character and a command line to run after creating the
+ corresponding device(s) and before removing, ala:
+
+ hdc root:cdrom 660 *ln -s $MDEV cdrom
+
+ The $MDEV environment variable is set to the name of the device.
+
+ The special characters and their meanings are:
+ @ Run after creating the device.
+ $ Run before removing the device.
+ * Run both after creating and before removing the device.
+
+ Commands are executed via system() so you need /bin/sh, meaning you
+ probably want to select a default shell in the Shells menu.
