Somewhat.

    This has to be some Fedora-specific weridness, are they on Lua 5.37 already or something in which all globals are gone? Can't reproduce on any of Lua 5.1 .. 5.3 or LuaJIT 2.0

    Fedora-specific weirdness? Fedora ships Lua 5.3, yes. But Prosody in Fedora is only using Lua 5.1. If you assume some Fedora specific issue, please let us follow up this. However, I would need an ejabberd dump then. Important is that './configure --runwith=<lua-name>' doesn't get applied to 'tools/ejabberd2prosody.lua' through, but that is an upstream issue, not a Fedora one.

    I got bit by this too.. Fedora 23.

    This is either an incompatible Lua build or a broken Lua build. We really can't support either.
