I have similar problem, I think. My problem was permission to write 
(using sudo) in /gnu/store/ when I needed to enable my correct synaptics 
(I copied 50-synaptics.conf file to /gnu/store/.../xorg.conf.d/), so I 
needed remount /gnu/store/ (sudo mount -o remount,rw /gnu/store) to copy 
this file.
