adding udev rule

[Jean-Baptiste Volatier]

Hi!

I am trying to setup a udev rule to enable wake on lan on my ethernet adapter. 
For that I have added to my config.scm:

(define %wol-udev-rule
  (udev-rule
    "90-wol.rules"
    (string-append "ACTION==\"online\", KERNEL==\"enp0s25\", "
                   "PROGRAM+=\"/usr/bin/ethtool -s enp0s25 wol g\"\n")))


And:

(operating-system
  ...
  (services
   (append
    (list ...
          (extra-special-file "/usr/bin/ethtool"
                    (file-append ethtool "/sbin/ethtool"))
          (udev-rules-service 'wol %wol-udev-rule)
          ...
    %desktop-services))
   ...
)

Somehow this does not work, it might be because of my udev rule but on the 
other hand the output of "udevadm test /devices/ ... /enp3s0" does not show my 
90-wol.rules so it looks like it is not added ?
Any thoughts ?
