[Libguestfs] appliance VM won't start, can't find /init, but /init is in the image.

Hi, Still trying to get libguestfs appliance test to work on Ubuntu Lucid. I figured out my umask was causing problems and fixed that. now I'm on to a new problem. libguestfs-test-tool reports the following: febootstrap: mounting new root on /root febootstrap: chroot /proc/uptime: No such file or directory execl: /init: No such file or directory febootstrap: debug: listing directory / 2 d . 040755 4096 88619:5000 2 d .. 040755 4096 88619:5000 11 d lost+found 040700 16384 0:0 12 d bin 040755 4096 23083:5000 13 d boot 040755 4096 23083:5000 14 d etc 040755 4096 23083:5000 109 d lib 040755 4096 23083:5000 156 d sbin 040755 4096 23083:5000 157 d usr 040755 4096 23083:5000 534 d var 040755 4096 23083:5000 3701 - init 100750 3264 23083:5000 Note, init is indeed a file (a shell script). I checked the root and initrd images, and they both have init (the initrd has an init binary, the root has a shell script that starts udev etc).
