Of course you're right. I forgot we already had a "script" postaction (well, I
see that only XeTeX is using it for now).

I guess adding .lua -> texlua is easy.

The tricky part is, we want to call the -sys version of the script. Please
excuse me if I'm suggesting something stupid, but couldn't we extend postaction
script so that it can use executables under bin/ ? That way, we could benefit
from the symlinks/wrapper for the -sys variant, and wouldn't need to worry about
guessing the interpreter.

Another point: it is possible that a package with this postaction script
mkluatexfontdb is installed while luaotfload is not. In that case, tlmgr should
silently skip the postaction IMO. (The problem doesn't arise with XeTeX since
the script is included in the xetex package itself.)

Manuel.
