OK, I understand why the binary in texmf-linux is still OK. Because
you didn't manage to update it with the new one. If you have your own
luatex binary, copy luatex into bin/texlua, disable updating bin
folder, update ConTeXt and finally copy your own luatex binary over
the one provided by the installation (texmf-linux/bin/luatex).
