True, but you don't get to take advantage of the space savings this way and you can't have a unified tree without resorting to symlink, filesystem, or auto mounter hacks. With real fat binaries you only have to keep one copy of certain segments or perhaps one copy per endianness, but certaintly less copies then the total number of architectures. If you wanted to just implement fat packages you might actually want to *not* use a ransom access archive format so you could at least get better compression of the repeted segments of the binaries. An intresting tradeoff question. -- Brooks --=20 Any statement of the form "X is the one, true Y" is FALSE.
