capslock_to_control not working on Yosemite

[jabley]

I've included osx::keyboard::capslock_to_control in my setup. I'm having problems getting it to work.

boxen::personal::includes:
  - osx::keyboard::capslock_to_control

This alters the settings like so:

> ioreg -n IOHIDKeyboard -r | grep -E 'VendorID"|ProductID' | \
awk ' { print $4 }' | paste -s -d'-\n' - | \
xargs -I{} sh -c 'defaults -currentHost read -g "com.apple.keyboard.modifiermapping.{}-0"'
(
        {
        HIDKeyboardModifierMappingDst = 2;
        HIDKeyboardModifierMappingSrc = 0;
    }
)

If I use the Keyboard preferences pane to remap left control to capslock, and capslock to control, I get the following changes in the defaults.

> ioreg -n IOHIDKeyboard -r | grep -E 'VendorID"|ProductID' | \
awk ' { print $4 }' | paste -s -d'-\n' - | \
xargs -I{} sh -c 'defaults -currentHost read -g "com.apple.keyboard.modifiermapping.{}-0"'
(
        {
        HIDKeyboardModifierMappingDst = 2;
        HIDKeyboardModifierMappingSrc = 0;
    },
        {
        HIDKeyboardModifierMappingDst = 0;
        HIDKeyboardModifierMappingSrc = 2;
    },
        {
        HIDKeyboardModifierMappingDst = 0;
        HIDKeyboardModifierMappingSrc = 10;
    }
)

If other people can confirm this looks good, I can try to alter the existing puppet class to reflect this.
