I'm worried: alpha/alpha-1 8471242752 bytes arm/arm-1 7612305408 bytes hppa/hppa-1 8148635648 bytes i386/i386-1 8735232000 bytes ia64/ia64-1 9016291328 bytes m68k/m68k-1 8810422272 bytes mips/mips-1 7869827072 bytes mipsel/mipsel-1 7720431616 bytes powerpc/powerpc-1 10134548480 bytes powerpc/powerpc-2 355729408 bytes s390/s390-1 8079792128 bytes sparc/sparc-1 8143155200 bytes src/src-1 9058893824 bytes Some of the architectures may fit fine on DL DVD (alpha, arm, mips, mipsel, s390, sparc), but i386 is looking even bigger than manty's set and src is much bigger again. m68k, ia64 and powerpc (over 10G!) are really going to have problems if we care about this. Recent experience on the lists suggests that the most common architectures for DVDs are i386 and powerpc. Both of these are going to need significant pruning at the moment if we care about a single-disc install. At the moment, ppc may not even fit on 2 DVDs! -- Steve McIntyre, Cambridge, UK. steve@einval.com We don't need no education. We don't need no thought control.
