Indeed, but it's the output of the "name" property in Lua's font object.
But the output of the same property for LInux Libertine is "Linux 
Libertine O"

fc-list -v | grep Libertine
    family: "Linux Libertine O"(s)
    fullname: "Linux Libertine O"(s)
    postscriptname: "LinLibertineO"(s)
    ...

fc-list -v | grep -i "adobe.*garamond"
    family: "Adobe Garamond Pro"(s)
    fullname: "AGaramondPro-SemiboldItalic"(s) "Adobe Garamond Pro Sb 
Italic"(s) "Adobe Garamond Pro Semibold Italic"(s)
    <no postscriptname!>
    ...

This seems I need the "family" value, which seems what LilyPond expects 
(and which seems reasonable for user input).
Somehow it seems random that "fullname" is the right thing for LInux 
Libertine and some other fonts.

What I meant is: can I safely assume that by inserting a space before 
every uppercase letter I get back to the family name? I strongly doubt 
that ...

I hope so, although the relevant section in the LuaTeX manual doesn't 
give a hint.

I'll try to find one ...
