- If you are adventurous you can add the following to cont-new.mkiv
\enablemode[*nofonts]
This will postpone font loading and will be default soon. This saves
runtime when you use another font than latin modern. When no font is
loaded before the first \starttext, modern will kick in. A side effect
is that any text typeset before \starttext will not show up in the
output. If you observe that, you need to setup a bodyfont explicitly
beforehand. In practice there should be no problems. The delayed
loading is somewhat tricky but has been tested for a while.
If felt adventurous and I found the following problem:
%%%% minimal example %%%%
\usetypescript[libertine]
\setupbodyfont[libertine,12pt]
\starttext
\startitemize[1]
\item one
\item two
\stopitemize
\stoptext
%%%% end %%%%
Can you test if
\setupbodyfont[libertine,12pt]
\starttext
$ABC \bullet \star$
\stoptext
also fails?
Yes. Full log here

Sorry, but I can't typeset math unless various parameters have
been set. This is normally done by loading special math fonts
into the math family slots. Your font set is lacking at least
the parameter mentioned earlier.

Seems like a bug. If no math typescripts are defined, the fallback
should have been loaded. (In any case, the libertine typescript should
use either txfonts or perhaps xits as the default math fonts).
