You shouldn't increase LCONF_VERSION unless LAYER_CONF_VERSION increases, and 
certainly it shouldn't be increased beyond the value of LAYER_CONF_VERSION 
(currently this is 6 in meta-yocto, 5 in OE-Core); why it would be telling you 
it had updated it if you did do that I don't know, that's certainly not 
intended behaviour.

Cheers,
