>From man udev:
       The udev rules are read from the files located in the default rules
       directory /lib/udev/rules.d/, the custom rules directory
       /etc/udev/rules.d/ and the temporary rules directory
       /run/udev/rules.d/. All rule files are collectively sorted and
       processed in lexical order, regardless of the directories in which they
       live. However, files in /etc/udev/rules.d/ take precedence over files
       with the same name in /lib/udev/rules.d/; this can be used to ignore a
       default rules file if needed.
