First I'd like to note that it does take a about 1 minute for the first
boot since it has to generate new keys and erase the last bit of flash
(after a firstboot). 

Did you flash the correct image? It sounds like you flashed a core
image to the router (which does not include luci).

Also (in regards to another message sent), the only difference between
libreCMC images and the ones that ThinkPenguin ships are the inclusion
of the openvpn-openssl package.
