It looks quite > reasonable and universal (as opposed to distro-specific) this way. Package.path in luatex is initialized according to the stock lua distribution's default. And by that I mean the stock lua from www.lua.org, not the patched debian version ... and I am sure you see where this is going ... > PS: I'm aware I can fix package.path in my script before using require, I just > think it would be better if it worked OOTB. ... and it would have worked OOTB, if Debian had not altered the lua settings. Anyway, have you tried setting LUA_PATH in the environment? If that does not work, then we can think of altering luatex itself. Best wishes, Taco
