ACTION=="add|change", SUBSYSTEM=="block", RUN+="/usr/sbin/l_tunedisk /dev/%k"

Oct 23 08:06:49 lmds1 systemd: Started udev Coldplug all Devices.
Oct 23 08:06:49 lmds1 systemd-udevd: failed to execute '/usr/sbin/l_tunedisk' '/usr/sbin/l_tunedisk /dev/sdb': No such file or directory
Oct 23 08:06:49 lmds1 systemd-udevd: Process '/usr/sbin/l_tunedisk /dev/sdb' failed with exit code 2.
Isn't this supposed to be on the server side only?
