- 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 %%%%
It fails because itemize seems to require some math characters (the
bullets) and the libertine font seems not to have them. lmodern don't
kick in, it just fails:
Works for me with the latest minimals. For Libertine bullets you can use the following:
\setupbodyfont[libertine]
\definesymbol[1][•] % otherwise LMMathSymbols10-Regular
\starttext
\startitemize
\item one
\item two
\stopitemize
\stoptext

Just to be sure I've updated the Minimals, but with 

 \enablemode[*nofonts]

in cont-new.mkiv it fails.

I don't need a workaround, because I can comment out the *nofonts in the
cont-new.mkiv (which was added by myself). I was just reporting a
problem, as asked (IIRC).
