Simple %e enumerations never worked reliably outside of udevstart and
udevstart is no longer recommended to use.

 If udev receives a device event, it matches its configured rules against the available device attributes provided in sysfs to identify the device. Rules that match, may provide additional device information or specify a device node name and multiple symlink names and instruct udev to run additional programs as part of the device event handling.
