Programs will get called whenever the -device naming program in the system has either named a new device and -created a /dev node for it, or when a /dev node has been removed from -the system due to a device being removed. - -The directory tree under /etc/dev.d/ dictate which program is run first, -and when some programs will be run or not. The device naming program -calls the programs in the following order: - /etc/dev.d/DEVNAME/*.dev - /etc/dev.d/SUBSYSTEM/*.dev - /etc/dev.d/default/*.dev - -The .dev extension is needed to allow automatic package managers to -deposit backup files in these directories safely. - -The DEVNAME name is the name of the /dev file that has been created, or -for network devices, the name of the newly named network device. This -value, including the /dev path, will also be exported to userspace in -the DEVNAME environment variable. - -The SUBSYSTEM name is the name of the sysfs subsystem that originally -generated the hotplug event that caused the device naming program to -create or remove the /dev node originally. This value is passed to -userspace as the first argument to the program. - -The default directory will always be run, to enable programs to catch -every device add and remove in a single place. - -All environment variables that were originally passed by the hotplug -call that caused this device action will also be passed to the program -called in the /etc/dev.d/ directories. Examples of these variables are -ACTION, DEVPATH, and others. See the hotplug documentation for full -description of this - -An equivalent shell script that would do this same kind of action would -be: - DIR="/etc/dev.d" - export DEVNAME="whatever_dev_name_udev_just_gave" - for I in "${DIR}/$DEVNAME/"*.dev "${DIR}/$1/"*.dev "${DIR}/default/"*.dev ; do - if [ -f $I ]; then $I $1 ; fi - done - exit 1; - - |
