Steev Klimaszewski 780c324559 all: Move extras to be installed later 
Due to extras pulling in the modifications to the plymouth config file,
we were getting prompted whether to overwrite it or not.  There is a
bug to fix plymouth but currently upstream needs help to work on it.
Work around it for now.
