While this should work it is not necessary for many 32-bit applications. They will run fine if called directly outside the chroot. The 32-bit libraries need to be listed in /etc/ld.so.conf and /lib/ld-linux.so.2 (the 32-bit linker) needs to be present (possibly as symlink to /chroot32/lib/ld-linux.so.2). Then, many applications will run fine in the 64-bit environment and they can easily call 64-bit applications. Matthias -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
