Yes, that register patch may be needed on some Linux systems; I'll add this to the documentation. Redbean can't use the system Lua, so it comes bundled with its own Lua interpreter (Lua 5.4; there is also work being done to allow LuaJIT or Luau to be embedded instead). The modules need to be put in the .lua directory within redbean archive; redbean searches within its archive, so you don't need to set LUA_PATH/LUA_CPATH. I have instructions on how to get examples working included in the examples (https://github.com/pkulchenko/fullmoon/tree/more-links#examples https://github.com/pkulchenko/fullmoon/tree/more-links#examp...) section. In terms of the size, this includes MbedTLS and SQLite, so if you don't need those modules, you can compile redbean without them, which should reduce the size considerably.
