linux – schroot无法登录

$mkdir -p /srv/chroot/squeeze64
$debootstrap --arch amd64 squeeze /srv/chroot/squeeze64 http://ftp.debian.org/debian/
$cat /etc/schroot/schroot.conf
    [squeeze64]
    description=Whatever
    directory=/srv/chroot/squeeze64
    users=ajtack
    root-users=ajtack
    type=directory

进入chroot失败的原因如下：

$schroot -c squeeze64
E: Failed to change to directory '/var/lib/schroot/mount/squeeze64-d1d6ed5e-b217-4319-94ee-ff0422a75671': No such file or directory

我不知道如何调试这个.出了什么问题？

附加信息：从详细的运行.
