ah, ok, so that luatex update even broke the context updater (i didn't 
realize that luatex would quit on an unknown option instead of just 
ignoring it)

anyway, as there is no way we can deal with such incompatible updates 
out of our control, one can install lmtx which should be fine (and 
likely has the right luatex too, or you can pick up some luatex from the 
compile farm which should work ok with recent scripts)

summary:

- there is a luatex update that breaks context but is needed for other 
macro packages, and in principle such a fundamental incompatinility 
should go along with a context update

- the update therefore needs a patched mtxrun although one never patches 
mtxrun directly unless doing that off-context-zip (it's now how mtxrun 
is created)

- the luat-fmt is the one that should get two "--socket" snippets 
because otherwise a context run can fail in some scenarios

- new observation: older engines might fail with new scripts but I'm not 
going to check for versions (in fact, if we weren't aware of the issue 
contexts would fail everywhere once such an update rolls out)

So .. not much we can do about it other than just manually adapt when a 
situation arises. The good news is that luametatex is unaffected and 
that is what the majority used.

Hans

ps. I assume new luatex binaries have to be put into the old mkiv/mkii 
installers when they ship with a newer script. Kind of a mess.
