Here's the direct download link: $ wget https://people.debian.org/~glaubitz/chroots/debian-x32-unstable.tar.gz Checksum should be: $ sha256sum debian-x32-unstable.tar.gz 010844bcc76bd1a3b7a20fe47f7067ed8e429a84fa60030a2868626e8fa7ec3b debian-x32-unstable.tar.gz Seems to work fine here (on a distro kernel) even if I extract all the files as a non-root user and do: ~/s/debian-x32-unstable> fakechroot /usr/sbin/chroot . /usr/bin/dpkg -l | tail -2 ERROR: ld.so: object 'libfakechroot.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored. ii util-linux:x32 2.31.1-0.5 x32 miscellaneous system utilities ii zlib1g:x32 1:1.2.8.dfsg-5 x32 compression library - runtime So that 'dpkg' instance appears to be running inside the chroot environment and is listing x32 installed packages. Although I did get this warning: ERROR: ld.so: object 'libfakechroot.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored. Even with that warning, is still still a sufficiently complex test of x32 syscall code paths? BTW., "fakechroot /usr/sbin/chroot ." crashes instead of giving me a bash shell. Thanks, Ingo
