I'm not sure how much other elements of my test harness are contributing to reproducing the problem. -eric --snip-- # setup chroot mount -o bind /dev /mnt/9/dev mount -o bind /sys /mnt/9/sys # test mmap via ldconfig doesn't produce lots of errors chroot /mnt/9 ldconfig -C /tmp/testldconfig.cache > $LOG.log 2>&1 if [ -s $LOG.log ]; then echo "FAIL" else echo "SUCCESS" fi
