Novell LINUX ENTERPRISE SERVER 11 - ADMINISTRATION Administration Manual page 155

RUN
Tell udev to add a program to the list of programs to be executed for this device.
Keep in mind to restrict this to very short tasks to avoid blocking further events
for this device.
LABEL
Add a label where a GOTO can jump to.
GOTO
Tell udev to skip a number of rules and continue with the one that carries the label
referenced by the GOTO key.
IMPORT{type}
Load variables into the event environment such as the output of an external program.
udev imports variables of several different types. If no type is specified, udev tries
to determine the type itself based on the executable bit of the file permissions.
• program tells udev to execute an external program and import its output.
• file tells udev to import a text file.
• parent tells udev to import the stored keys from the parent device.
WAIT_FOR_SYSFS
Tells udev to wait for the specified sysfs file to be created for a certain device. For
example, WAIT_FOR_SYSFS="ioerr_cnt" informs udev to wait until the
ioerr_cnt file has been created.
OPTIONS
The OPTION key may have several possible values:
• last_rule tells udev to ignore all later rules.
• ignore_device tells udev to ignore this event completely.
• ignore_remove tells udev to ignore all later remove events for the device.
• all_partitions tells udev to create device nodes for all available partitions
on a block device.
