I'm having a great deal of difficulties deploying custom user fonts using the luatex loading sequence with either the new or old simplefonts setups. 

Is there a wiki page which is most correct on how to go from "no user font loaded" to "define font family, \input knuth" with instructions? I've got the feeling I've been looking in the wrong places.

For the most desirable user font, can we presume 14.04 and the system package fonts-roboto? (ttf) or I'm happy to attach the .otf compiled versions I made if you think that worthwhile. We certainly can use whatever directories we want -- but I'm just unsure about how to most consistently achieve this.

Cheers,
