- mdev is a mini-udev implementation: call it with -s to populate
- /dev from /sys, then "echo /sbin/mdev > /proc/sys/kernel/hotplug" to
- have it handle hotplug events afterwards. Device names are taken
- from sysfs.
+ mdev is a mini-udev implementation for dynamically creating device
+ nodes in the /dev directory.

bool "Support /etc/mdev.conf"
default n
depends on MDEV
help
- The mdev config file contains lines that look like:
-
- hd[a-z][0-9]* 0:3 660
-
- That's device name (with regex match), uid:gid, and permissions.
+ Add support for the mdev config file to control ownership and
+ permissions of the device nodes.
- 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.)
+ For more information, please see docs/mdev.txt
config FEATURE_MDEV_EXEC
bool "Support command execution at device addition/removal"
default n
depends on 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.
+ This adds support for an optional field to /etc/mdev.conf for
+ executing commands when devices are created/removed.
- Commands are executed via system() so you need /bin/sh, meaning you
- probably want to select a default shell in the Shells menu.
+ For more information, please see docs/mdev.txt
