Actually the lua variant is -- more efficient, especially when multiple calls to kpsewhich are involved. The lua -- library also gives way more control. -- When libraries used here are updates you can run -- -- mtxrun --selfmerge -- -- to update the embedded code. After that you might need to run -- -- mtxrun --selfupdate -- -- to copy the new script (from scripts/context/lua) to location where -- binaries are expected.
