Files in this directory contain configuration for systemd-udev.service, a
daemon that manages symlinks to device nodes, permissions of devices nodes,
emits device events for userspace, and renames network interfaces.

See man:udev(7) for an overview of the configuration file format, and
man:systemd-udevd.service(8) for a description of service itself.

Use 'systemd-analyze cat-config udev/rules.d' to display the effective config.
