Next alpha think about enabling pretty much all compression types or at least including them in all Linux releases (including PI) from now on. Ubuntu/Debian/Raspbian all include unrar-free, lhasa, p7zip-full, and for a long time have had arj. So all are available if not installed. You can still leave them as not used, but you might as well include them. As you can guess lhasa handles lda and lzh, p7zip-full handles all 7z except rar which has a module that you can add for it.
