Shouldn't it be possible to first install /lib32 and then ld-linux and libc6 (amd64) at the same time (probably by hand using a static linked shell). After that most old i386 packages should automagicly use libc6 from /lib32. Then one would somehow have to change apt and dpkg's idea of which architecture you use, probably by installing them by hand (i.e. unpacking with cpio and tar or copying from a i386 chroot previously created with pbuilder or similar). After that some kind of "dpkg -l | xargs apt-get --reinstall install" should do the rest. You should try that in a chroot first and of course keep a GRML CD at hand. bye, -christian-
