+config BUSYBOX_CONFIG_FEATURE_MDEV_EXEC
+ bool "Support command execution at device addition/removal"
+ default n
+ depends on BUSYBOX_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.
