Hi, One problem of mixed usage of mkiv (with luatex) and lmtx (with luametatex) is that in the later we use a different (initial) context runner. Basically all platforms are now handled the same (in mkiv there was a stub and no texlua, in unix something shebang with texlua because of argument passing limitations). However, the main context script can be told to use a specific engine: context --luatex foo.tex so in principle one can use both lmtx and mkiv with the same binary tree, given that luametatex and luatex are both present and that luametatex is in charge. For that reason the latest lmtx installer now (for the time being) also includes the luatex binary (plus mkiv files needed) so that one can install lmtx and run both engines. Instead of the --luatex switch one can also force the engine in the usual way with "% engine=luatex" at the top line of the source file (but no pdftex and xetex in this installer). FWIW, the lmtx installation ships with the latest experimental luatex binary but normally that should not have consequences, but it does permits testing occasional updates.
