Indexing fonts

[Peter Flynn]

I am trying to update my information on what faces and fonts are 
available to the user of a newly-installed TeX Live WITH the extra fonts 
(both via the TUG download and via the texlive-full.deb and 
texlive-fonts-extra.deb) IMMEDIATELY after installation, BEFORE any 
additional user intervention.

I think what I'm missing is whether either route automatically updates 
the system's font index, either via a system-provided font installation 
indexer or via a utility such as fc-cache. I am assuming that fonts 
installed by the operating system itself at original install time are 
already indexed.

I guess the question is really whether XeLaTeX or LuaLaTeX can 
immediately use fontspec to load (eg) \setmainfont{Accanthis} or if a 
manual indexing task has to be performed.
