Debian packages are as usual in deb http://www.tug.org/texlive/Debian/ luatex/ deb-src http://www.tug.org/texlive/Debian/ luatex/
I realized it could be useful to make my binaries available as well (Mac OS X Intel and Sparc Solaris), so here they are: http://arthur.reutenauer.eu/luatex/binaries/ Unlike Norbert, I really only deliver the raw binaries without any packaging, so people interested in downloading them will have to figure out a way of making them fit in their installation. For Mac OS X, I compiled on an Intel processor and I don't know how to make “universal” binaries yet so it'll only work on Intel. And as far as Solaris is concerned, I haven't built the latest snapshot because it requires a little bit of tweaking. Arthur
