texlive-latex-base provides ltluatex.lua. This file is generated from ltluatex.dtx.
ltluatex.dtx contains literal tabs in the embedded Lua sources. Upon unpacking the dtx file to generate the file ltluatex.lua these tabs are erroneously converted to the string “^^I”, which breaks the lualatex tool and all other tools that derive from it. It is easy to patch ltluatex.dtx, but this will lead to rebuilding 3480 dependent packages. -- Ricardo
