What are the matching rules for udev in Linux?
In Linux, udev’s matching rules are used to match devices based on their properties. Udev utilizes a series of rules to determine which device should be handled by which device driver. These rules can be based on device properties such as device path, device type, device manufacturer, and more. The matching rules of udev are typically defined in rules files under the /etc/udev/rules.d/ directory, which use the .rules extension. Udev rules use keywords like SUBSYSTEM, ATTR, KERNEL, and others to match device properties and determine which device driver should handle them. The matching rules of udev can be customized as needed to meet the user’s device management requirements.
