[LEDE-DEV] [PATCH 2/2] base-files: fix config storing on generation

[Koen Vandeputte]

Skip that last part ..

Someone installed a folder inside /etc/config in the custom package 
(named network.d ....)  argh ...
During my testing below .. (copy new files to the config folder) the 
folder sometimes got copied along ...

This closes it for me too ..
