I also guess it is something wrong with the file system type, then I
checked the file system type when mount rootfs_lucid64 to container depot
path "mnt/", it's overlayfs for suse other than aufs for ubuntu10.04, but
it does support overlayfs for if you changed to overlayfs on ubuntu10.04,
the app can alslo be started successfully.
After that I found when stack the container file system, the command
"mount" exec with "-n" option, which means do not write the mount info to
/etc/mtab, but when exec on suse, it does write to the /proc/mtab. Another
strange phenomenon is that the mount command is called by "unshare -m",
which means do not share mount namespace with the calling process, but I
can see the mounted files in the calling UTS namespace in fact, even add
the "--make-rprivate" option to command mount does not work. that confused
me too much.

wshd is simply reporting  the pivot_root  failure. It looks like
you're getting an EINVAL from the call which implies warden is running in
an unexpected environment.
If I were to guess, I'd say that the container depot does not live on an
expected file system type or location...
As far as I'm aware, no work has been done to make warden run under
anything but Ubuntu or CentOS recently but it's possible someone has. If
nobody else has any hints, you'll likely have to look through the code and
work out what's going on.
