execute your ld-linux.so.2 directly. Something like /path/to/your/chroot/lib/ld-linux.so.2 /path/to/your/executable (combined with an LD_LIBRARY_PATH hack, so that the ld-linux that you execute looks for libraries in the directory you specify instead of /usr.) good times, Vineet -- http://www.doorstop.net/ -- http://www.debian.org/
